1.8V 10Gbps USB Type-C® DP-Alt Linear Redriver


The PI2DPX1217 is a non-blocking USB Type-C® DP-Alt mode linear ReDriver™ 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 waveforms from transmitter side to receiver side, this can help to optimize the overall channel link adjustment conducted by the system
transmitter and receiver 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 and linearity adjustments support the eye diagram opening.
The CTLE EQ gains, flat gains and linearity are individually programmable 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.
