PI2DPX2020

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 operation 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 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 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 programmable on each channel for flexible tuning via the I2C register settings. The on-chip signal detector and DP AUX Listener enable the ReDriver to enter the USB power saving mode or the DP D3 power down mode to further reduce standby power consumption.
