Description
3.3V power supply
CML input channels. With Selectable input termination between 50Ω to internal Vbias or
60kΩ to ground.
Set the state of chip; With internal 200kΩ pull-down resistor
“High” means NO receiver termination detection and for debug mode.
“Low” means normal operation mode with receiver termination detection.
Set the equalization of the channels. Tri-level input pin. With internal 100kΩ pull-up resis-
tor and 100KΩ pull-down resistor.
Output Selectable output termination between 50Ω to internal Vbias or 2kΩ to internal Vbias.
Input
Set de-emphasis of output CML buffer. Tri-level input pin. With internal 100kΩ pull-up
resistor and 100kΩ pull-down resistor.
GND Supply Ground.
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.
