Cyclic Redundancy Check (CRC) Nightmares

Cyclic Redundancy Check (CRC) Nightmares

By Robert Haller

This article is a continuation of SI/PI problems and lessons that I have toiled through and would love to share with the community. I received positive feedback on my last article Mysterious Case of the Flapping Switch, so I will continue to try to capture some interesting stories. Hopefully this will help others to quickly debug their lab nightmares.

Analog Devices

Analog Devices’ 2MHz Boost/SEPIC/Inverter Features 4A, 60V Power Switch & 4 uA IQ

Analog Devices, Inc. announces the Power by Linear™ LT8364, a current mode, 2MHz step-up DC/DC converter with an internal 4A, 60V switch. It operates from an input voltage range of 2.8V to 60V, and is suitable for applications with input sources ranging from a single-cell Li-Ion battery to multicell battery stacks, automotive inputs, telecom power supplies and industrial power rails.

Passive Plus


Passive Plus, Inc. (PPI) now offers extended-values for the Traditional NP0, Hi-Q 0505 (.055” x .055”) -- now available up to 1,000pF; and 1111 (.110” x.110”) -- now available up to 10,000pF (.01uF). The 0505 and 1111 have an increased Operational Temperature up to 200°C. These parts exhibit Low ESR/ESL, Low Noise, High Self-Resonance as well as ultra-stable performance over temperature.

Mainstream SERDES Design and Analysis

So you're designing SerDes links running between 5 and 25 Gbps? What do you need to look at to make sure that your board will work the first time, and meet your performance goals? It depends on the protocol, and can involve time-domain metrics such as eye masks or frequency-domain metrics such as insertion loss. Attendees will learn requirements for simulating popular SerDes protocols and new analysis methods.
