When a ring isn’t really a ring

EDN Network - 5 hours 48 min ago

Early in my engineering career, I worked with a couple of colleagues on an outside project. We had a concept for a security system for gaming arcades. At the time, arcades were very popular, hosting games like Pac-Man, Space Invaders, and Pinball. One of the business problems, though, was the theft of coins from the gaming machines. Apparently, when staff members were emptying the coin boxes, they would pocket a handful of coins. Theft in these arcades was said to be around 25%.

Do you have a memorable experience solving an engineering problem at work or in your spare time? Tell us your Tale

Our concept for preventing these thefts was a device that consisted of two parts. One micro-based device was installed in each of the arcade games. This counted the coins as they entered the slot. Then, periodically, the total coin count and game ID were transmitted, via the power line, to the back office. In the back office was the receiver. It monitored the power line and collected all the transmissions from the various games. This back-office device was also connected to a telephone landline, and once a day, the central office would call into the back-office device to have the daily data sent to it. The hand count of coins could then be reconciled with the electronic coin count from all the machines.

My colleagues and I divided up the work, with one doing the schematic and PCB prototypes. Another did the enclosures, labeling, etc. I did the firmware for the two pieces of equipment. After many months of evening work, we had a system that performed just as we expected. We also got a test site identified to install a complete system. As the arcade was more than 1000 miles away, we had someone at the other end install the system. After a few days, we got a call from the arcade operator telling us the office device would not answer the phone call into it. The hardware design was rechecked to see if the opto-isolator, signaling the firmware of a high voltage on the ring line, was designed correctly to take into account lower-level ring voltages—no issue there. This issue fell on me as it appeared to be a firmware issue. I tested my firmware dozens of times with various changes using an actual landline—it always worked. After many days of testing, I announced that I could not find any issues.

As a last resort, we had the hardware engineer fly to the arcade site with a raft of test equipment. After only a few hours, he called and said he had found the issue. The standard for ringing for a landline is defined by ANSI T1.401-1988 section 5.4.2, which I followed for the firmware. According to this standard, the ring cadence consists of 2 seconds of ringing followed by 4 seconds of silence. The phone system, in the town where the arcade was, followed this…sort of. During the ring, there was a short dropout ( about 80 ms, if I remember correctly). So, what the firmware saw was about 1 second of ring, no ring for 80 ms, then 920 ms of ring, and then 4 seconds of silence. The firmware, noting that the ring was only one second long, determined that it wasn’t a valid ring and therefore wouldn’t answer. The discovery of the issue was long, difficult, and expensive. The fix was easy to implement in firmware. After updating the firmware, the arcade system worked very well (we never got rich off it, though…another, non-technical, story).

The takeaway here is not how to construct landline phone answering firmware; those days are long gone. But the lesson here is that when you have an issue, suspect everything. We continued to have discussions on why the system would not answer the phone when we knew it was sensing the ring. We never thought that maybe the cadence, defined by an ANSI standard, would not be correct. Why the town’s telephone ring system had an 80 ms gap was never discovered, but it obviously didn’t meet the spec. So, if you can’t find a problem in your device, maybe it’s the other device(s) you’re connecting to. And at that point, the other system needs to be checked against its specs.

PCB design tips for EMI and thermal management in 800G systems

EDN Network - 13 hours 21 min ago

As the industry accelerates toward 800G Ethernet and optical interconnects, engineers face new challenges in managing electromagnetic interference (EMI) while ensuring signal integrity at unprecedented speeds. The transition to 112G pulse amplitude modulation 4-level (PAM4) SerDes introduces faster edge rates and dense spectral content, elevating the risk of radiated and conducted emissions.

Simultaneously, compact module form factors such as QSFP-DD and OSFP force high-speed lanes, DC-DC converters, and control circuitry into tight spaces, increasing the potential for crosstalk and noise coupling. Power delivery noise, insufficient shielding, and poor return path design can easily transform an 800G design from lab success to compliance failure during emissions testing.

To avoid late-stage surprises, it’s critical to address EMI systematically from the PCB level up, balancing stack-up, routing, and grounding decisions with high-speed signal integrity and practical manufacturability.

This article provides engineers with actionable PCB design strategies to reduce EMI in 800G systems while maintaining high performance in data center and telecom environments.

Layout considerations

For chip-to-chip 112G PAM4 signaling, the key frequency is the Nyquist frequency, which is half of the baud rate. PAM4 encodes 2 bits per symbol.

  • Therefore, the baud rate (symbol rate) is half of the bit rate. For 112 Gbps, the baud rate is 112 Gbps / 2 = 56 Gbaud (gigabaud).
  • The Nyquist frequency is half of the baud rate. So, the Nyquist frequency for 112G PAM4 is 56 Gbaud / 2 = 28 GHz.

The maximum insertion at 29 GHz for 112G medium range PAM4 is 20 dB. Megtron 7 offers a low dissipation factor (Df) of 0.003 at 29 GHz, which is adequate for 112G. Df of 0.003 is squarely in the “very low loss” category. It means that the material will dissipate a minimal amount of the signal’s energy, allowing more of the original signal strength to reach the receiver.

This helps preserve the critical amplitude differences between the PAM4 levels, enabling a lower bit error rate (BER). Low-cost FR-4 material typically has Df value of 0.015, which is excessive for 112G PAM4.

Aperture and shielding effectiveness

To avoid EMI, the wavelength relationship is essential, especially when considering wires or openings that may serve as unintentional antennas. An EMI shield’s seam, slot, or hole can all function as a slot antenna. When this opening’s dimensions get close to a sizable portion of an interfering signal’s wavelength, it turns into an effective radiator, letting EMI escape, perhaps failing the radiated emission test in an anechoic chamber.

As a general guideline, the maximum size of any aperture should be less than λ/20 (one-twentieth of the wavelength) of the highest frequency of concern to achieve efficient EMI shielding. See Figure 1 for typical airflow management openings.

Figure 1 Airflow apertures and shielded ventilation are shown for airflow management. Source: Author

The wavelength is calculated as lambda = c / f = (3 * 108) / (28 * 109) = 10.7 mm

Opening dimension = lambda / 20 = 0.536 mm

To reduce EMI problems, all apertures for equipment that operate at or are vulnerable to 28-GHz signals should ideally be less than 0.536 mm. The permitted dimensions for apertures decrease with increasing frequencies.

Routing guidelines and via stub impact at 112G PAM4

The spacing rule between two differential pairs is different for TX-to-TX and TX-to-RX. Generally, the allowed serpentine routing length for 112G PAM4 is less than previous speeds. Serpentine lines have less impact on a differential pair that is weakly connected.

A via stub is the unused portion of a through-hole via that extends beyond the layer where the signal transitions (Figure 2). For example, if a signal goes from the top layer to an inner layer via a through-hole, the part of the via extending from that inner layer to the bottom of the board forms a stub.

Figure 2 The diagram provides an overview of PCB via stub. Source: Author

f = c/(4*L*√ℇeff)

f = resonant frequency of a via stub = 28 GHz

c = speed of light = 3 x 108 m/s

L = Length of via stub = 1.533 mm = 60.35 mils

ℇeff = 3.05 at 28GHz

A via stub length of ~60 mils will resonate near 28 GHz in Megtron 7. For 112G PAM4 designs, this length is too long and can cause serious signal integrity issues.

Power considerations

Generally, 800G transceivers consume between 13 W and 18 W per port for short range but exact value is mentioned in module manufacturer datasheet. These transceivers contain 8 lanes for 112G to transmit 800G. A 1RU appliance with 32 QSFP-DD would need 25.6T switch. See Figure 3 for a simplified diagram of 1RU appliance with one ASIC.

Figure 3 Airflow management is shown for 1U high-speed systems incorporating a single ASIC. Source: Author

  • Power consumption for 112G PAM4 SerDes is high (typically 0.5–1.0 W per lane). For example, SerDes system will consume worst-case scenario Power = 8 * 1 W = 8 W.
  • Tcase_max = 90°C, Tambient_max = 50°C. Rth = (90 – 50) / 8 = 5° C/W. System designers should ensure heatsink and thermal interface material provides ≤ 5 ° C/W.
  • Q = Power to be dissipated (watts). ΔT = Allowable air temperature rise across the system (°C). Conversation factor = 3.16
  • CFM = Q* 3.16/ΔT = 2000 * 3.16/15 = 421
  • In 1RU, engineers use multiple 40 x 40 x 56 mm high-RPM fans for airfield distribution that typically pushes ~25-30 CFM. Fans required = 421/25 = 16.8 ≈ 17 fans. Accommodating this high number of fans is difficult because external power supplies occupy rear space.

Design recommendations

As 800G hardware and 112G PAM4 SerDes become standard in next-generation data center and telecom systems, engineers face a multifaceted design challenge: maintaining signal integrity, controlling EMI, and managing thermal constraints within high-density 1RU systems.

Careful PCB material selection, such as low-loss Megtron 7, precise routing to minimize via stub resonance, and disciplined aperture management for shielding are essential to avoid signal degradation and EMI test failures. Simultaneously, the high-power density of 800G optics and SerDes require advanced thermal design, airflow planning, and redundancy considerations to meet operational and reliability targets.

By systematically addressing EMI and thermal factors early in the design cycle, engineers can confidently build 800G systems that pass compliance testing while delivering high performance under real-world conditions. Doing so not only avoids costly late-stage redesigns but also ensures robust deployment of high-speed systems critical for the evolving demands of cloud and AI workloads.

PWM + Quadrac = Pure Power Play

EDN Network - Wed, 07/23/2025 - 16:58

It’s just a fact, I’m curiously fond of topologies that combine PWM switching and filtering circuitry with power handling devices like adjustable voltage regulator chips. This scheme makes power-capable DACs with double-digit wattage outputs. For example, “0 V to -10 V, 1.5 A LM337 PWM power DAC.”

Wow the engineering world with your unique design: Design Ideas Submission Guide

The simple circuit in Figure 1 joins this favored family but makes its siblings look weak and wimpy by upping the power ante by more than a factor of 10. It attains output capabilities over a kilowatt and gets there with a total parts count of only nine inexpensive discretes. Here’s how it works.

Figure 1 The quadrac Q2 conduction-angle triggering time constant = R1C1 / DF, where DF is the PWM duty factor from 0 to 100%.

The power control method in play is variable AC phase angle conduction via a quadrac (also sometimes called an alternistor). Quadracs are bidirectional thyristors that comprise the dual functions of a triac (to do the power switching) and an integrated diac (to trigger the triac).

They’re popular in applications like variable-speed power tools and lamp dimmers because they’re cheap, efficient, and durable. What’s also nice is that the only support components they need for AC power control are a small potentiometer and a timing capacitor (both also cheap) to adjust triggering delay and thereby the phase angle of conduction, thence power output

Q2 is wired in exactly that traditional way ,except that opto-isolator Q1 and R1 fill the role of the pot. The duty factor (DF) of Q1’s PWM input sets its average conductance and thereby the effective trigger delay from a

DF = 1 minimum of ~1.7 ms for an upper 95% output power, down to a DF = 0 delay that’s longer than the entire 8.33 ms AC half-cycle. Which is to say: OFF. The PWM cycle rate isn’t critical but should be at least 10 kHz to avoid possible annoying beat frequencies since it’s not synchronized with the 60 Hz AC cycle.

The relationship between DF, phase angle, and percent power output is equal to the time integral of [(Vpk*sin(r)) 2], which is shown in Figure 2.

Figure 2 The (Vpk*sin(r))2 power output versus the PWM DF. The right axis is the voltage of the trigger capacitor (C1), the left axis is the fraction of the full output power versus trigger phase, and the x-axis is the AC phase in radians.

Because Q1, unlike Q2, isn’t bidirectional, the D1-4 diode bridge is necessary to keep it upright despite 60-Hz phase reversals. Q1’s typical current transfer ratio of 80% makes ~10 mA of PWM drive current necessary. Current limiter R2’s 330 Ω assumes a 5-V rail and a low impedance driver and will need adjustment if either assumption is violated. The Vc1 trigger voltage is 38 V ±5 V with ±3 V max asymmetry. These tolerances place a limit on DF versus power precision.

The full throttle Q3 power output efficiency is around 99%, but Q2’s max junction temperature rating is only 110 °C. Adequate heatsinking of Q2 will therefore be wise if outputs greater than 200 W and/or toasty ambient temperatures are expected.

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have been accepted since his first contribution back in 1974.

Is the World Ready for Driverless Cars? Consumer Sentiment and Self-Driving Cars Market Potential

ELE Times - Wed, 07/23/2025 - 13:37

The concept of self-driving cars has long fascinated the world, and in the last decade, this once-futuristic vision has begun taking tangible form on real-world roads. Backed by artificial intelligence, advanced sensor systems, and increasingly robust regulatory frameworks, autonomous vehicles are moving from prototypes to potential mainstream adoption. However, the question remains: Is the world truly ready for driverless cars?

As consumer sentiment evolves and the Self-driving Cars Market matures, industry leaders and policymakers must align innovation with public trust. In this blog, we’ll explore the current state of market potential, public readiness, technological advancements, and the barriers still standing in the way.

Consumer Perception: Trust Is Still Evolving

One of the biggest hurdles facing the Self-driving Cars Market isn’t technological—it’s psychological. Despite increasing awareness and media coverage, consumer trust in autonomous driving systems remains mixed.

According to various global mobility surveys, while many people express curiosity and even excitement about autonomous vehicles (AVs), a significant portion remains skeptical. Safety concerns, such as fear of accidents due to software glitches or hacking, rank among the top reasons for hesitation.

This sentiment is supported by recent studies, including those cited in Fairfield Market Research reports, which show that over 60% of consumers still prefer to be in control behind the wheel. Interestingly, younger demographics and tech-savvy consumers are more open to embracing driverless technology, signaling a gradual generational shift in acceptance.

Market Potential: A Multibillion-Dollar Industry in the Making

Despite consumer hesitations, the Self-driving Cars Market is poised for remarkable growth. According to Fairfield Market Research, the market is projected to grow exponentially over the next decade, driven by advancements in AI, LiDAR, radar, and 5G connectivity. From autonomous taxis and delivery vehicles to personal self-driving cars, this sector is brimming with transformative potential.

Forecasts indicate that the market could reach several hundred billion dollars in value by 2032, thanks to increasing investment by both automakers and tech giants. Companies like Tesla, Waymo, NVIDIA, Baidu, and General Motors are pouring billions into R&D, strategic partnerships, and road testing to get ahead of the curve.

What sets this market apart is its ability to serve a wide range of applications—from mobility as-a-service (MaaS) to long-haul trucking, ride-sharing platforms, and even emergency services. The convergence of self-driving capabilities with electrification is further fueling this trajectory, positioning autonomous EVs as the future of smart mobility.

Technology Advancements That Make Autonomous Driving Possible

The backbone of autonomous vehicles lies in a suite of intelligent technologies designed to mimic human perception and decision-making. These include:

  • Advanced Driver-Assistance Systems (ADAS): Core to self-driving features like lane-keeping, adaptive cruise control, and emergency braking.
  • LiDAR and Radar: Crucial for depth perception, obstacle detection, and maintaining 360-degree awareness.
  • Machine Learning and AI: These enable real-time learning and predictive decision-making based on road conditions, traffic, and behavior of other drivers.
  • 5G Connectivity: Enables ultra-fast communication between vehicles (V2V) and infrastructure (V2X), essential for safe navigation and traffic management.

Tech innovations continue to improve the reliability and scalability of autonomous driving systems. What was once limited to controlled environments is now being tested—and increasingly trusted—on busy city streets and highways.

Regulatory Landscape: Countries Taking the Lead

While technology marches forward, regulation remains a critical piece of the puzzle. Governments around the world are experimenting with frameworks to ensure the safe integration of AVs into public infrastructure.

The United States, through the National Highway Traffic Safety Administration (NHTSA), has issued federal guidance and pilot programs to promote innovation while safeguarding public welfare. Similarly, countries like Germany, Japan, and China are crafting regulatory sandboxes to foster autonomous mobility.

The European Union’s push for standardized vehicle safety norms and China’s rapid AV testing initiatives further demonstrate that the regulatory environment is evolving, albeit at different speeds across regions.

The harmonization of safety standards, liability protocols, and cybersecurity norms will play a major role in determining how quickly driverless vehicles move from limited trials to widespread adoption.

Urban Infrastructure and the Readiness Gap

Beyond consumer acceptance and regulatory progress, physical infrastructure plays a pivotal role in enabling the adoption of driverless vehicles. Smart traffic signals, connected roadways, digital mapping, and real-time traffic data are prerequisites for safe AV deployment.

However, most cities are still in the early stages of integrating such infrastructure. While some smart cities like Singapore, San Francisco, and Dubai are leading with AV-friendly road networks and IoT integration, the majority of the world still lags behind.

The readiness gap between developed and developing economies could pose a major challenge for the global adoption of autonomous vehicles. Investments in digital infrastructure, maintenance of road quality, and real-time data exchange capabilities will be crucial in bridging this divide.

Ethical Considerations and Data Privacy

With the rise of autonomous mobility comes a wave of ethical dilemmas. From decision-making in crash scenarios to potential bias in AI algorithms, the question of who is accountable when things go wrong is still murky.

Moreover, self-driving cars collect vast amounts of data—from location tracking and biometric identifiers to driving behavior. Ensuring data privacy and cybersecurity will be a top priority as the Self-driving Cars Market scales.

Consumer concerns about surveillance, hacking, and misuse of personal data must be addressed through transparent policies, encryption technologies, and government oversight.

Economic Impact and Job Disruption

As the market evolves, the ripple effects on employment and industry structures are inevitable. While autonomous vehicles will generate new job roles in software development, data science, and fleet management, they are also expected to disrupt traditional roles—especially in trucking, taxi services, and delivery.

Balancing automation with human employment is an area that governments, labor unions, and corporations must address proactively. Reskilling and upskilling the workforce will be essential to ensure a smooth transition to a more autonomous transportation ecosystem.

A Road Paved with Caution and Opportunity

So, is the world ready for driverless cars? The answer is complex. Technologically, we are closer than ever. From AI to vehicle connectivity, innovation has created a solid foundation. Yet public perception, regulatory clarity, infrastructure readiness, and ethical concerns still need time and effort to align.

The Self-driving Cars Market holds extraordinary promise, offering a future with safer roads, efficient traffic systems, and more accessible mobility options. But realizing this vision will require global collaboration between automakers, tech firms, regulators, and consumers.

As reported by Fairfield Market Research, the journey toward widespread adoption of autonomous vehicles is not a sprint but a marathon. The path ahead is filled with both promise and pitfalls—but with the right strategies in place, a driverless future is no longer just a dream.

PCB design error

PCB design error

I work for an electronics company who design their own boards. Yesterday I was fault finding a board that had the IS07810DWW ic fitted but the board wasn't working. After looking at the schematic and the technical datasheet i found that they had design the board to use IS07810DW and fitted the IS07810DWW. Unfortunately the pin layouts are completely different and the DW version is 6mm too thin to fit on the pad profile of the DWW. So yea. We have 250 of these on the shelf.

This shows you should always get your work peer reviewed before getting the boards made.
