PI3EQX7502B
5.0Gbps, 1-port, USB3.0 ReDriver™
Pericom Semiconductor’s PI3EQX7502B 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. PI3EQX7502B sup-
ports two 100Ω Differential CML data I/O’s between
the Protocol ASIC to a switch fabric, over cable, or to ex-
tend the signals across other distant data pathways on
the user’s platform. The integrated equalization circuitry
provides flexibility with signal integrity of the signal be-
fore 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
deviceentersalowpowerstandbymode. ThePI3EQX7502Balso
includes a fully programmable receiver detect function.
When the RXD-EN pin is pulled high, automatic receiver de-
tection will be active. The receiver detection loop will be ac-
tive 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.
