PI2DPT1021Q 1.8 V Bidirectional USB Type-C DP-Alt Retimer

The Diodes automotive-compliant PI2DPT1021Q is a bit-level retimer providing receiver-adaptive equalization, compensating for channel losses up to -23 dB at 5 GHz signals.

The device has 10 Gbps data handling, and supports DisplayPort (DP) 1.4 and USB 3.2 standards for automotive USB Type-C applications such as rear seat entertainment and active cables.

The PI2DPT1021Q has 4:4 channels, supporting system-on-chip (SoC) devices with an integrated USB/DP crossbar switch with I²C. The I²C is used to select:

• Four-lane DP
• Two-lane DP and one-lane USB 3.2 Gen2
• One- or two-lane USB 3.2 Gen2

The PI2DPT1021Q complies with USB power management states for active mode (U0) and power-saving modes (U1, U2, U3). The PI2DPT1021Q is packaged in the very small X1-QFN2845-32 (0.4 mm pitch) package, supports AEC-Q100 Grade 2, and operates across a -40°C to +105°C temperature range.

The bidirectional design provides flexibility when the DFP and UFP signal flows are swapped, which supports active cable applications and signal flow selection. Diodes also provides the PI2DPT1021 commercial-grade device for industrial applications.
