Xilinx® expects the use of the MCDP6000 Retimer along with the DisplayPort 1.4 RX Subsystem solution. MCDP6000 as a retimer provides better SI features. As a retimer, the MCDP6000 removes the random and ISI jitter from video source. The MCDP6000 configuration is controlled through an I2C interface. The DisplayPort 1.4 RX Subsystem design needs an external I2C controller to configure the Retimer.
Because the DisplayPort software driver handles the required MCDP6000 configuration, you do not have to control the MCDP6000 retimer. If the MCDP6000 is managed by a control other than the DisplayPort software driver, contact MegaChips (mca_support@megachips.com) for detailed programming information.
