The PI2EQX22024 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 USB3.2 standards for USB Type-C® data mode operation. The operation configurations are programmable via I2C interface to select 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.

With the merit of the bit level ReTimer design, PI2EQX22024 has very low latency from signal input to output (< 1ns) that serves good interoperability among various USB devices.
