Description

The PI3DPX1203 is DisplayPort compliant, 8Gbps link speed, single differential channel Linear ReDriver with Link Training transparent mode. Since DisplayPort source and sink-side device are unaware of the Linear ReDriver, they never generate AUX link training transactions, and pass through all the AUX transactions between source and sink-side devices. PI3DPX1203 provides programmable input equalization, linear swing and flat gain control to optimize output over a variety of physical mediums by reducing intersymbol interference. The integrated linear equalization circuitry  provides flexibility with signal integrity of the signal before  and after the ReDriver. A low level input signal detection and output squelch function is provided.
