The DIODES Advantage

The PI2DPX1264 is a 1.8V, 13.5Gbps, low-power, DP 2.1/eDP

1.5 linear ReDriver with AUX listener that provides optimized

signal integrity.

The PI2DPX1264 is a 13.5Gbps

DisplayPort (DP) 2.1 UHBR13.5/eDP 1.5

linear ReDriver in a 4-to-4 configuration

operated by a 1.8V power supply.

The device supports UHBR13.5, UHBR10,

HBR3, HBR2, HBR, and RBR under various

DP speeds. With its on-chip AUX channel

listener, the device automatically monitors

the system operation status and can enter

D3 power saving mode. The AUX listener

also monitors the link speed rate to auto-

select pre-defined equalization (EQ) and

flat-gain (FG) for optimized signal integrity

(SI).

The PI2DPX1264’s 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.

Its CTLE equalizers are implemented at the

inputs of the ReDriver to compensate for

channel loss and reduce inter-symbol

interface (ISI) jitter. Programmable FG

adjustment enables opening of the eye

diagram. The CTLE EQ gains and flat gains

are individually programmable on each

channel for flexible tuning via I2C register

setting.

The PI2DPX1264 is available in the very

small 32-pin X2QFN (XUA32), with a

2.85mm x 4.5mm footprint, and operates

across the -40

C to +85C industrial

temperature range.
