PI2EQX502E
1.8V 5.0Gbps, 1-port (2-Channel) USB3.0 ReDriver™
Pericom Semiconductor’s PI2EQX502E 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. PI2EQX502E 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. If the input signal
level of the channel falls below the active threshold level
(Vth-) then the outputs are driven to the common mode
voltage.
The PI2EQX502E 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.
