The PI2EQX502T is a low power, 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. PI2EQX502T
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 channels’ input signal level (on xI+/-) determines whether
the output is active.
The PI2EQX502T 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.
