Product Description

PI3EQXDP1201 provides the ability to reduce signal jitter by transmission line effects to enable longer cable length on the 5.4Gbps DisplayPort1.2 signals. Built-in Sync_Request_Auto_Test mode enables users to complete Displayort link status through Aux channels in minutes.

Intergrated AUX decoder can support Displayport link training. It can decipher the link training message and automatically configure Displayport differential signal outputs with the best pre-emphasis and output swing level settings.

Displayport Aux decoder enable to configure Equalization setting for the different Displayport cable lengths automatically through link traning process.
