By YT Tso, Anne Wu and Jessy Chen
Introduce:
PI3EQX501(I) is a 1-channel low power high performance 5.0Gbps signal ReDriver designed for USB3.0
protocol. The device provides programmable Equalization (EQ) and De-Emphasis (DE) to optimize
performance over a variety of physical mediums by reducing Inter-Symbol Interference (ISI)
