Description
Diodes' PI3DPX1203 is the Displayport compliant, up to 4 channel,
8.1 Gbps Linear Redriver with Link Training transparency sup-
port. 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 cong-
ure with pin-strapping or I2C programing to optimized Main Link
high speed signals over a variety of physical medium by reducing
inter-symbol interference. Pericom's Linear Redriver technology
can deliver 2 times better additive jitters performance than tradi-
tional Redrivers.
Linear Equalizer always provide very exible component place-
ment, cascade connection and easy adjustment aer the Redriver
location changes during the product development events.
