Diodes Incorporated PI2DPT1021Q Bi-directional ReTimer is a high-performance, automotive-grade, and bit-level ReTimer designed for USB Type-C and DP1.4 applications. This ReTimer features receiver adaptive CTLE and transmitter 3-tap equalization, which can compensate for channel loss of up to -23dB in 5GHz signal transmission. The PI2DPT1021Q ReTimer supports data rates up to 10Gbps, making it ideal for high-resolution video and fast data transmission. The integrated AUX/SBU switch allows automatic mapping of DisplayPort AUX signals to USB Type-C SBU lines, simplifying design and reducing external components. This ReTimer supports multiple configuration modes, including 4-lane DP, 2-lane DP/1 lane USB3.2 Gen1x1/Gen2x1, 1/2 lane USB3.2 Gen1x1/Gen2x1 or USB3.2 Gen2x2, all controllable via an I2C interface.

The device includes features like Rx termination detection, LFPS detection, and an AUX listener for intelligent power and mode management. The PI2DPT1021Q ReTimer is AEC-Q100 Grade 2 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities, ensuring automotive-grade reliability. This bit-level ReTimer is ideal for automotive infotainment systems, smart cockpits, rear seat entertainment, and active cable applications.
