PI2EQX632E
1.8V 5.0Gbps, 2-port, USB 3.0 Mux/DeMux ReDriver
Description
Pericom Semiconductor’s PI2EQX632E is a low power, high
performance 5.0 Gbps 2-Port USB3.0 Mux / DeMux ReDriver™
designed specically for the USB 3.0 protocol.
The device provides programmable equalization, swing and
De-Emphasis to optimize performance over a variety of physical
mediums by reducing Inter-Symbol Interference.
PI2EQX632E 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. A low-level
input signal detection and output squelch function is provided
for each channel. Each channel operates fully independently.
The channels’ input signal level (on xI+/-) determines whether
the output is active. The PI2EQX632E also includes an adaptive
power management feature to maximize battery life for power
sensitive consumer devices.
