Diodes Incorporated PI2EQX22024 USB Type-C™ Bi-Directional ReTimer

Diodes Incorporated PI2EQX22024 USB Type-C™ Bi-Directional ReTimer contains a receiver adaptive CTLE and transmitter 3-tap equalization, which can compensate channel loss up to -23dB for 5GHz signal transmission. The device offers USB 3.2 standards for USB Type-C data mode operation. The operation configurations are programmable through the I²C interface to select 1-lane USB3.2 Gen1x1/Gen2x1, 1/2-lane USB3.2 Gen1x1/Gen2x1 or USB3.2 Gen2x2.

The Diodes PI2EQX22024 utilizes a standard 1.8v V_dd power supply, achieving good power-saving management. The ReTimer complies with USB link power management states for active mode (U0) and power saving mode (U1, U2, U3). USB Rx detection continuously monitors the plug condition of the TX terminals. Additionally, the LFPS signal detector detects the LBPM (LFPS Based on PWM Message) of USB mode. The PI2EQX22024 has very low latency with the merit of the bit level ReTimer design, from signal input to output (<1ns) which serves good interoperability among various USB devices.
