Tiny 32-pin X2QFN, (0.4 mm pitch) (XUA)

The PI2DPX1217 is a non-blocking USB Type-C DP-Alt mode

linear RedriverTM in 4-to-4 configuration operated by 1.8v power

supply. It supports four operation modes through I2C bus setting

for USB3.2 Gen2, USB3.2 Gen2/2-lane DP1.4/DP2.0 (UHBR10),

4-lane DP1.4/ DP2.0 (UHBR10) or USB3.2 Gen2x2 with speed up

to 10Gbps per channel. It swaps the high speed channels under

the flip and non-flip plug in compliance to Type-C connector with

the integrated AUX crossbar switch for SBU pins.

The non-blocking linear Redriver design ensures the differential

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

forms from transmitter side to receiver side, this can help to opti-

mize the overall channel link adjustment conducted by the system

transmitter and receiver with DFE. The CTLE equalizers are imple-

mented 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 pro-

grammable on each channel for flexible tuning via I2C register

settings. USB channel by-pass mode is initialized at power-on as

default mode to support factory setting especially for the system

with only Type-C connector.
