PI3EQX501B
5.0Gbps, 1-channel, USB3.0 ReDriver™
Description
Pericom Semiconductor’s PI3EQX501B is a low power, high per-
formance 5.0 Gbps signal ReDriver™ designed specifically for the
USB 3.0 protocol. The device provides programmable equaliza-
tion and De-Emphasis to opmize performance over a variety of
physical mediums by reducing Inter-Symbol Interference.
PI3EQX501B supports one 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. The channels’ input signal level determines whether
the output is active.
The PI3EQX501B also includes a receiver detect function.
The receiver detection loop will be active again if the corre-
sponding 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.
