Description

The PI2DPX2023A is a 20Gbps DP2.1 linear ReDriver™ in 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 en-

ter D3 power saving mode.

The non-blocking linear ReDriver design ensures that the dif-

ferential signals conveying pre-shoot and de-emphasis equal-

ization 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 flat gain adjustments support the eye diagram

opening. The CTLE EQ gains and flat gains are tuned via pin

strap control.
