PI2DPT1021Q

Description

The PI2DPT1021Q is a bit level ReTimer with receiver adaptive CTLE and transmitter 3-tap equalization which can compensate channel loss up to -23dB for 5GHz signal transmission. It supports DP1.4 and USB3.2 standards for USB Type-C® DP ALT mode operation. The operation configurations are programmable via I2C interface to select 4-lane DP, 2-lane DP/1 lane USB3.2 Gen1x1/ Gen2x1, 1/2 lane USB3.2 Gen1x1/Gen2x1 or USB3.2 Gen2x2.

To achieve good power saving management, this device uses the common 1.8V Vdd power supply. It complies with USB link power management states for active mode (U0) and power saving mode (U1, U2, U3). USB Rx detection monitors the plug condition of the TX terminals continuously. The LFPS signal detector detects the LBPM (LFPS Based PWM Message) of USB mode.

Under DisplayPort operation, the AUX Listener will monitor the AUX communication for data rate, lane count, swing & pre-emphasis setting and power saving D3 mode setting. The SINK side HPD connection signal is set via I2C register by the system PD controller. The integrated AUX/SBU switch maps the DisplayPort AUX+/- pins and to the Type-C SBU1/SBU2 pins automatically.

The bi-directional design provides the flexibility if DFP and UFP signal flow is swapped which is a convenient setting on the fly for active cable application or it can give more layout option for signal flow selection.

With the merit of the bit level ReTimer design, PI2DPT1021Q has very low latency from signal input to output (< 1ns) that serves good interoperability among various USB and DP devices.
