PI3HDMI511AZLEX

Specialized Overview

The PI3HDMI511AZLEX is an HDMI 1.4 re-driver designed for source applications by Diodes Incorporated. It re-drives TMDS signals originating from dual-mode DisplayPort or HDMI sources to maintain signal integrity at data rates exceeding 2.2Gbps. The device incorporates internal source termination for high-speed transmission and supports both AC-coupled and DC-coupled main link inputs. It features a built-in 5V-to-3.3V level shifter for DDC channels, eliminating the need for external FETs. The HPD_SRC pin utilizes an open-drain buffer design requiring an external pull-up resistor.

Specialized Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors. Confirm datasheet alignment with AN352 application guidelines. Ensure packaging specifications match project requirements. Validate RoHS compliance status prior to integration. Review ordering suffixes for specific package or tape-and-reel variations.

Specialized Selection Notes

Select this component for source-side HDMI 1.4 implementations requiring signal re-driving. Consider internal termination and level shifting capabilities when designing PCB layouts. Evaluate dual-mode DP compatibility if interfacing with mixed-source environments. Verify external component requirements for DDC and HPD channels during schematic capture.

Specialized Part Context

This part belongs to the PI3HDMI511A family of HDMI re-drivers manufactured by Diodes Incorporated (formerly Pericom Semiconductor). The series targets source applications where signal degradation over traces or cables necessitates active re-driving. The AZLEX suffix typically denotes specific packaging or reel configurations within the product line.

Specialized Replacement Considerations

Consult official substitution lists for equivalent HDMI re-drivers. Verify pinout compatibility and electrical parameter alignment before replacing. Check for updated datasheets regarding revised feature sets or packaging changes in successor models.
