PI2DPX1263XUAEX

Signal Buffers, Repeaters, Splitters Overview

The PI2DPX1263XUAEX is a non-blocking DisplayPort 2.0/1.4 linear ReDriver manufactured by Diodes Incorporated, designed to enhance signal integrity in high-speed video applications. It features a four-channel configuration supporting data rates up to 10Gbps per channel (UHBR10), as well as HBR3 (8.1Gbps), HBR2 (5.4Gbps), and RBR modes. The device operates on a single 1.8V ±5% power supply and includes an integrated AUX channel listener for automatic D3 power saving mode activation based on DPCD register traffic. Key electrical parameters include ultra-low latency of less than 300ps, individual programmable CTLE gain, flat gain, and output linearity controls via I2C slave interface (up to 1MHz). It functions within an industrial temperature range of -40°C to +85°C and is housed in a compact 32-pin X2QFN package measuring 2.85mm x 4.5mm.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and compliance status. Confirm that the component meets RoHS 3 and halogen-free requirements if mandated by local regulations. Cross-reference the part number with authorized distributors to validate authenticity and traceability. Ensure the procurement specifications align with the industrial temperature range and voltage requirements of the target application.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal regeneration for DisplayPort links operating at UHBR10 or lower speeds. The integrated AUX listener simplifies power management logic by automatically detecting link states. Consider the compact X2QFN footprint for space-constrained portable devices. Verify that the host controller supports the required I2C communication protocol for configuring equalization settings. Ensure the power supply network can provide stable 1.8V operation across the full industrial temperature range.

Signal Buffers, Repeaters, Splitters Part Context

The PI2DPX1263 belongs to Diodes Incorporated’s family of linear ReDrivers, which are engineered to extend transmission distances and maintain signal quality in high-bandwidth digital interfaces. This specific model targets DisplayPort ecosystems, bridging the gap between source transmitters and display receivers. It complements other variants in the series that support higher speeds like UHBR13.5 or different channel configurations, offering a balanced solution for standard 10Gbps per lane applications.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct replacements must match the 4-channel configuration, 10Gbps speed capability, and X2QFN-32 package dimensions. Verify compatibility with existing PCB layouts and I2C addressing schemes. Alternative parts from other manufacturers may require schematic modifications due to differences in pinout or control register definitions.
