PI3DPX1235Q2ZLBEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1235Q2ZLBEX is a DisplayPort (DP) 2.1 UHBR13.5 and USB 3.2 Gen 2 linear ReDriver signal conditioner manufactured by Diodes Incorporated. It integrates a 6:4 active multiplexer to support data rates up to 13.5 Gbps, compliant with VESA DP Alt 2.1 UHBR13.5 and USB 3.2 Gen 2 standards. The device accommodates various channel configurations including single-channel USB 3.2, dual-channel USB 3.2 and DP 2.1 UHBR13.5, or four-channel DP 2.1 UHBR13.5, all multiplexed to a USB Type-C interface. It operates at a maximum supply voltage of 3.3 V, supports an I2C clock frequency of 1 MHz, and functions within a temperature range of -40°C to +105°C. The component is housed in a W-QFN-40 package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix '2ZLBEX' against official Diodes Incorporated documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with the W-QFN-40 footprint and validate that the -40°C to +105°C operating temperature range meets the target environmental requirements. Cross-reference the I2C control interface requirements with the system controller capabilities before integration.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring simultaneous support for DisplayPort 2.1 UHBR13.5 and USB 3.2 Gen 2 protocols over a single USB Type-C connector. The integrated 6:4 mux reduces external component count compared to discrete solutions. Confirm that the PCB layout supports the W-QFN-40 package dimensions and thermal dissipation needs for the specified 3.3 V operation.
