Signal Integrity
Signal integrity, the focus of DesignCon, is at the heart of all high-speed serial links. Without good signal integrity from a transmitter and across a transmission lave, a receiver can't distinguish between and logic 1 and a logic 0. The Signal-Integrity collection features articles that explain how to measure signal characteristics such as jitter and bit-error rate.
