PI3EQX7502
5.0Gbps, 1-port, (2-Channel), USB 3.0 ReDriver™
Pericom Semiconductor’s PI3EQX7502 is a low power, high
performance 5.0 Gbps signal ReDriver™ designed specifically
for the USB 3.0 protocol. The device provides programmable
equalization, De-Emphasis, and input threshold controls to
optimize performance over a variety of physical mediums by
reducing Inter-Symbol Interference. PI3EQX7502 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. When the channels
are enabled EN_x# = 0 and operating, that 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. In addition to signal conditioning, when EN_x# = 1, the
device enters a low power standby mode. The PI3EQX7502 also
includes a fully programmable receiver detect function.
When the RxDet pin is pulled high, automatic receiver detection
will be active. The receiver detection loop will be active again
if the corresponding channel’s signal detector is idle for longer
than 25mS. 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.
