Diodes Incorporated PI2DPX2023A 20Gbps DP2.1 Linear ReDriver™
Diodes Incorporated PI2DPX2023A 20Gbps DP2.1 Linear ReDriver™ features a 4-to-4 configuration operated by a 1.8V power supply. The device supports UHBR20 (20Gbps), UHBR13.5 (13.5Gbps), UHBR10 (10Gbps), HBR3 (8.1Gbps), HBR2 (5.4Gbps), HBR (2.7Gbps) and RBR (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 optimizes channel link adjustments by transmitting differential signals that carry pre-shoot and de-emphasis equalization waveforms from the transmitter to the receiver. This process enhances the performance of the system's transmitter and receiver, which are equipped with DFE. The CTLE equalizers are implemented at the inputs of the ReDriver to compensate for the channel loss and reduce the ISI jitters. The flat gain adjustments support the eye diagram opening. CTLE EQ gains and flat gains are tuned via pin strap control.
