Description
Pericom's PI3DPX1203 is the Displayport compliant, up

transparency support. Displayport source-side and sink-side
devices communicate through the AUX transaction between
the source and the sink-side devices.

configure with pin-strapping or I2C programing to optimized
Main Link high speed signals over a variety of physical me-
dium by reducing inter-symbol interference. Pericom's Linear
Redriver technology can deliver 2 times better additive jitters
performance than traditional Redrivers.

ment events.
