Plano, Texas – Diodes Incorporated (Nasdaq: DIOD) today announces the automotive-compliant* PI2DPT1021Q, a new bit-level ReTimer designed to meet the rigorous demands of the automotive market. This device supports both DisplayPort™ (DP) 1.4 and USB 3.2 standards for USB Type-C® applications, such as infotainment and clusters, rear seat entertainment, smart cockpits, and active cables.
The PI2DPT1021Q is a 10Gbps ReTimer capable of handling the high-speed data transmission required by modern in-car systems. A key advantage of this device is its ability to maintain high-speed signal integrity by providing receiver adaptive equalization, which compensates for channel losses up to -23dB at 5GHz. It also features jitter cleaning capabilities and an adaptive continuous time linear equalizer (CTLE), along with selectable adjustment of a 3-tap transmitter.
The ReTimer offers flexible 4:4 channel operation, supporting system-on-chip (SOC) devices with an integrated USB/DP crossbar switch. Its configuration is programmable via an I²C interface, allowing selection of different modes including: four-lane DP 1.4 (HBR3), two-lane DP 1.4 (HBR3) and one-lane USB 3.2 Gen2, and one- or two-lane USB 3.2 Gen2.
With a bi-directional design, the PI2DPT1021Q provides flexibility for signal flow selection, which is particularly useful in active cable applications. It features very low latency (less than 1ns) from signal input-to-output, ensuring good interoperability between various USB and DP devices.
Power management is a key feature, with auto power-saving modes for both USB and DP. The device complies with USB power management states for active mode (U0) and power-saving modes (U1, U2, U3). For DisplayPort, it maintains D3 power-saving mode with a built-in AUX listener. It operates from a single 1.8V power supply.
Packaged in the very small X1-QFN2845-32 (2.85mm x 4.5mm, 0.4mm pitch), the PI2DPT1021Q optimizes PCB area, making it suitable for compact designs. The device operates across a wide temperature range of -40°C to +105°C. It is available at $1.65 in 5,000-piece quantities.
A standard compliance version, PI2DPT1021, is also available and suitable for industrial and commercial applications.
