Description

The DIODES™ PI2DPX2020 is a 20Gbps non-blocking USB

Type-C DP-Alt mode linear ReDriver in a 4-to-4 configuration

operated by a 1.8V power supply. It supports multiple opera-

tion modes through I2C bus settings for single-port USB4 Gen

3, dual-port USB4 Gen 3x2, 1-port USB4 Gen 3/2-lane DP2.0

(UHBR20) and 4-lane DP2.0 (UHBR20). It swaps the high

speed channels under the flip and non-flip plug connection

in compliance to Type-C connector with the integrated AUX

crossbar switch for SBU pins.

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 programmable flat gain adjustments support the

eye diagram opening.

The CTLE EQ gains and flat gains are individually program-

mable on each channel for flexible tuning via the I2C register

settings. The on-chip signal detector and DP AUX Listener en-

able the ReDriver to enter the USB power saving mode or the

DP D3 power down mode to further reduce standby power con-

sumption.
