A Practical Guide to Receiver Jitter Tolerance Testing, Part I :
Receiver Principles and Signal Impairment Tolerance Test
by Michael Fleischer-Reumann, Agilent Technologies
Years ago, digital communications crossed the 10 Gbit/s mark. As computer busses and interfaces approach this data rate constantly, signal integrity becomes an inevitable topic. The receiver (Rx) input is the location in digital transmission system where all problems accumulate, making it difficult for the related modules to properly perform their tasks.
This TechNote describes root causes for signal impairments, Rx topologies (clocking architectures), building blocks dealing with signal impairments, and necessary Rx-tolerance testing.
