PI2DPT1021XEAEX

Signal Buffers, Repeaters, Splitters Overview

The PI2DPT1021XEAEX is a bit-level ReTimer designed for USB Type-C DP Alt mode operation, supporting DP1.4 and USB3.2 standards. It features receiver adaptive CTLE and transmitter 3-tap equalization to compensate channel loss up to -23dB at 5GHz signal transmission. The device supports data rates of 10Gbps and operates on a single 1.8V power supply with +/-5% tolerance. Configuration is programmable via an I2C interface operating at speeds up to 1MHz. It offers low latency of less than 1ns from input to output and includes integrated AUX/SBU switches and listeners for sideband signal management and power control.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports configurable operations including 4-lane DP1.4, 2-lane DP/1-port USB3.2 Gen2, and USB 3.2 Gen2 x1 or x2 modes.
• Provides bi-directional design flexibility allowing dynamic swapping of DFP and UFP signal flows for active cable applications.
• Integrates an AUX channel crossbar switch to automatically map DisplayPort AUX pins to Type-C SBU pins.
• Includes adaptive continuous time linear equalizer (CTLE) and jitter cleaning capabilities without requiring a local reference clock.

Signal Buffers, Repeaters, Splitters Applications

• Source devices such as tablets, smartphones, notebooks, desktops, and all-in-one PCs
• PC docking stations and dongles (adapters)
• Active cables requiring bidirectional signal flow

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to ensure correct packaging and environmental compliance. Confirm that the XEA package code corresponds to the required 32-pin X1-QFN2845-32 form factor. Ensure procurement channels provide valid traceability for RoHS and halogen-free status requirements.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring high-speed signal integrity for USB Type-C and DisplayPort 1.4 interfaces. Consider its bidirectional capability if layout flexibility or active cable implementation is necessary. Verify that the system power architecture supports the specified 1.8V supply voltage and that I2C bus speeds do not exceed 1MHz.
