Diodes Incorporated


PI3DPX1203C is a 4 channel, DisplayPort 1.4 compliant, 8.1 Gbps HBR3 Linear Redriver with Link Training transparency support. Displayport source-side and sink-side devices communicate through the AUX transaction between the source and the sink-side
devices. Input Equalization, Voltage Swing and Flat Gain control can be configured with pin-strapping or I2C programing to optimize Main
Link high speed signals over a variety of physical medium by reducing inter-symbol interference. Diodes’ Linear Redriver technology can deliver 2 times better additive jitters performance than traditional Redrivers. Linear equalization always provides very flexible component placement, cascade connection and easy adjustment after the Redriver location changes during the product development events.
