Description
Pericom Semiconductor’s PI3EQX7742ST is a low power, high
performance 5.0 Gbps signal ReDriver designed specifically for
the USB 3.0 protocol. The device provides programmable equal-
ization, De-Emphasis, and input threshold controls to optimize
performance over a variety of physical mediums by reducing
Inter-SymbolInterference.PI3EQX7742STsupports four 100
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 PI3EQX7742ST
also includes a fully programmable receiver detect function.
When the RxDet pin is pulled high, automatic receiver detection
will be active. The device will then move to power down due
to inactivity.
