The DIODES™ PI2DPX2063 is a 20Gbps DP2.0/DP1.4 linear ReDriver in a 4-to-4 configuration operated by a 1.8v power supply. The device supports UHBR20 (DP2.0 20Gbps), UHBR13.5 (DP2.0 13.5Gbps), UHBR10 (DP2.0 10Gbps), HBR3 (DP1.4 8.1Gbps), HBR2 (DP1.2 5.4Gbps), HBR(DP1.1 2.7Gbps) and RBR(DP1.0 1.62Gbps) under various DisplayPort speeds. With the on-chip AUX channel listener, the device can automatically monitor the system operation status to enter D3 power saving mode.

The non-blocking linear ReDriver design ensures that the differential signals conveying pre-shoot and de-emphasis equalization waveforms from the transmitter side to the receiver side help optimize the overall channel link adjustment conducted by the system transmitter and receiver that has been equipped with DFE.

The CTLE equalizers are implemented at the inputs of the ReDriver to compensate the channel loss and reduce the ISI jitters. The programmable flat gain adjustments support the eye diagram opening. The CTLE EQ gains and flat gains are individually programmable on each channel for flexible tuning via I2C register settings.
