PI3VDP1431AZLSE

Specialized Overview

The PI3VDP1431AZLSE is a low-power dual-mode DisplayPort level shifter and redriver manufactured by Diodes Incorporated. It supports data rates up to 3.4 Gbps per lane, enabling 4K Ultra HD and Deep Color video formats. The device operates on a single 3.3V power supply and features integrated DDC buffering for the 'A' variant. Key electrical parameters include a typical standby current of 50 µA and an active supply current of 100 mA. It provides programmable equalization (2.5, 5, 7.5 dB) and pre-emphasis (0, 1.5, 2.5 dB). The component utilizes a 32-pin TQFN package measuring 3x6 mm.

Specialized Feature Summary

• Dual-mode operation as a DisplayPort level shifter with integrated 3.4Gbps redriver capabilities
• Integrated DDC buffer functionality in the 'A' version variant
• Automatic output squelch and HPD detection for intelligent power management
• Programmable signal conditioning with three-step input equalization and pre-emphasis controls

Specialized Applications

• Notebook computers
• Desktop computers
• HDMI sink systems connected to dual-mode DisplayPort sources

Specialized Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and lead-free status. Ensure the selected variant matches the required DDC configuration, as the base model differs from the 'A' version regarding internal circuitry. Cross-reference the full part number with official distributor catalogs to confirm availability and compliance details.

Specialized Selection Notes

Select the PI3VDP1431AZLSE when a DDC buffer is required rather than a passive switch. Confirm that the system design accommodates the 3.3V single-supply requirement and the 32-pin TQFN footprint. Evaluate the need for programmable equalization and pre-emphasis settings based on trace length and signal integrity requirements within the target application.

Specialized Part Context

This component belongs to the PI3VDP1431 family, which includes variants with different DDC configurations. The 'A' designation specifically indicates the inclusion of an integrated DDC buffer, distinguishing it from the standard switch version. It serves as a bridge between dual-mode DisplayPort sources and HDMI sinks, ensuring signal compliance and integrity.

Specialized Replacement Considerations

The datasheet notes pin-to-pin compatibility with the PI3HDMI511 and PI3HDX511A. Verify functional equivalence regarding DDC handling and signal levels before substituting these specific models.
