PI3EQX1002B
1-Port USB3.1 Gen-2 ReDriver
The PI3EQX1002B is a low power, high performance 10.0
Gbps 1-Port USB 3.1 linear ReDriver™ designed specically
for the USB 3.1 protocol. The device provides programmable
equalization, linear swing and at gain to optimize performance
over a variety of physical mediums by reducing Inter-Symbol
Interference. PI3EQX1002B 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 exibility with
signal integrity of the signal before the ReDriver. Each channel
operates fully independently. The channels’ input signal level
determines whether the output is active.
The PI3EQX1002B 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 (Slumber Mode)
due to inactivity.
