PI3EQX501B
5.0Gbps, 1-channel, USB3.0 ReDriver™
Features
Description
ÎÎUSB 3.0 compatible
Pericom Semiconductor’s PI3EQX501B 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 opmize performance over a variety of
physical mediums by reducing Inter-Symbol Interference.
ÎÎFull compliancy to USB 3.0 Super Speed standard
ÎÎOne 5.0Gbps differential signal pairs
ÎÎAdjustable Receiver Equalization
ÎÎ100Ω Differential CML I/O’s
PI3EQX501B supports one 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. The channels’ input signal level determines whether
the output is active.
ÎÎPin Configured Output Emphasis Control
ÎÎInput signal level detect and squelch function
ÎÎAutomatic Receiver Detect
ÎÎHost Mode Capable
ÎÎLow Power : 165mW
ÎÎAuto "Slumber" mode for adaptive power management
ÎÎPackaging: 8-Pin TDFN 2 x 2 mm
The PI3EQX501B also includes a 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.

“Low” means normal operation mode with receiver termination detection.
Set the equalization of the channels. Tri-level input pin. With internal 100kΩ pull-up resistor and 100KΩ pull-down resistor.
Power Management
Notebooks, netbooks, tablets and other power sensitive consumer devices require judicious use of power in order to maximize battery
life. In order to minimize the power consumption of our devices, Pericom has added an additional adaptive power management feature.
When a signal detector is idle for longer than 1.3ms, the channel will move to low power mode.
In the low power mode, the signal detector will still be monitoring the input channel. If a channel is in low power mode and the input
signal is detected, it will wake-up immediately. If a channel is in low power mode and the signal detector is idle longer than 6ms, the
receiver detection loop will be active again. If load is not detected, then the Channel will move to Device Unplug Mode and monitor
the load continuously. If load is detected, it will return to Low Power Mode and receiver detection will be active again per 6ms.
