Description

The PI2DPX1264 is a non-blocking DisplayPort 2.1/eDP1.5 lin-

ear ReDriver™ with four channels operated by 1.8V power supply.

The device supports UHBR13.5 (13.5Gbps), UHBR10 (10Gbps),

HBR3 (8.1Gbps), HBR2 (5.4Gbps), and RBR under various Dis-

playPort 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. and the AUX

Listener also monitors the link speed rate to auto select Pre-de-

fined EQ and FG for SI optimization.

The non-blocking linear ReDriver design ensures the differential

signals conveying pre-shoot and de-emphasis equalization wave-

form 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 equaliz-

ers 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 programma-

ble on each channel for flexible tuning via I2C register settings.
