PI1EQX512A
1.0V, 5.0Gbps, 1-port, USB3.0 ReDriver™
Description
Pericom Semiconductor’s PI1EQX512A is an ultra-low-pow-
er, high performance 5.0 Gbps signal ReDriver™ designed
specifically for the USB 3.0 protocol. The device provides
programmable equalization and De-Emphasis to optimize
performance over a variety of physical mediums by reducing
Inter-Symbol Interference. PI1EQX512A supports two 100Ω
Differential CML data I/O’s between the Protocol ASIC to a
switch fabric, over cable, or to extend the signals across other
distant data pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with
signal integrity of the signal before the ReDriver. A low-level
input signal detection and output squelch function is provided
for each channel. Each channel operates fully independently.
The PI1EQX512A also includes an automatic receiver detect
function. The receiver detection loop will be active again if
the corresponding channel’s signal detector is idle for longer
than 7.3mS. The channel will then move to Unplug Mode if
load not detected, or it will return to Low Power Mode (Slum-
ber Mode) due to inactivity.
