The Signal Integrity Perils of Power Via Stubs

By Istvan Novak

There are topics where even well-seasoned signal-integrity experts cannot agree on a unified answer. Probably one of the few exceptions is via stubs. We all tend to agree that high-speed signals are significantly degraded if the resonance frequency of a via stub attached to the signal path comes close to the signaling frequency. In contrast, we are usually not worried about having via stubs on power and ground planes and shapes. Does it mean they are completely harmless? Find out how and why.


Tektronix Optical Modules Boost Confidence with Industry’s Highest Sensitivity, Lowest Noise

Tektronix, Inc. introduced two new optical modules for its DSA8300 sampling oscilloscope that offers the high sensitivity and low noise, giving manufacturers the confidence they need to increase production capacity and improve yields for 400G designs moving into production. Tektronix also announced enhanced support for the latest 400G PAM4 TDECQ measurements with a software package optimized for 4 channel parallel processing for high throughput manufacturing test.

Analog Devices  

150VIN & VOUT Synchronous 4-Switch Buck-Boost Controller with Integrated Switching Bias Supply

Analog Devices announced the Power by Linear™ LTC3777, a 150V high efficiency (up to 99%) 4-switch synchronous buck-boost DC/DC controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V to 150V input voltage range operates from a high input voltage source, eliminating the need for external surge suppression devices, ideal for transportation, industrial and medical applications.

Best Design Practices for Systems with PDN Noise-Sensitive Circuits

Most of the power integrity focus is on high power devices, such as FPGAs and CPUs. Most power distribution networks (PDNs) also include sensitive circuits including LNAs, clocks, and PLLs, often even within the FPGAs. These sensitive circuits can be sensitive to microvolts of noise. The challenge is that over-designing the power supply adds unnecessary cost while under-designing the power supply results in suboptimal performance. In this webinar we’ll provide the essential information you need and allay your fears.
