The PI2DPX1263 is a non-blocking DisplayPort2.0/DP1.4 linear DisplayPort™ with four channels operated by 1.8V power supply. The device supports UHBR10 (10Gbps), HBR3 (8.1Gbps), HBR2 (5.4Gbps), and RBR under various DisplayPort speeds. With the on-chip AUX channel listener, the device can automatically monitor the system operation status to enter power saving mode via the DPCD register traffic check and activate the negotiated lane count for operation. The non-blocking linear ReDriver™ design ensures the differential signals conveying pre-shoot and de-emphasis equalization waveform messages from transmitter side to receiver side, which helps optimize the overall channel link adjustment conducted by the system transmitter and receiver 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 and linearity adjustments support the eye diagram opening. The CTLE EQ gains, flat gains, and linearity are individually programmable on each channel for flexible tuning via I2C register settings.
