PI3VDP1431AZLSEX

Specialized Overview

The PI3VDP1431AZLSEX 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, accommodating 4K Ultra HD, 3D video formats, and 48-bit Deep Color. The device operates on a single 3.3V supply with standby current below 1mA. It features programmable three-step input equalization (2.5, 5, 7.5 dB) and output pre-emphasis (0, 1.5, 2.5 dB). The 'A' suffix indicates an integrated DDC buffer rather than a passive switch. It utilizes a 32-pin TQFN package measuring 3x6mm.

Specialized Feature Summary

• Dual-mode operation as a DisplayPort level shifter and signal redriver for jitter improvement
• Integrated DDC buffer for source-side communication management
• Automatic output squelch and hot-plug detect functions for power saving
• Programmable equalization and pre-emphasis control steps

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the presence of the DDC buffer functionality associated with the 'A' designation. Ensure that the component matches the required 32-pin TQFN physical dimensions and thermal characteristics specified in the datasheet before finalizing procurement orders.

Specialized Selection Notes

Select this component when interfacing dual-mode DisplayPort sources with HDMI sinks requiring signal conditioning. The PI3VDP1431AZLSEX is appropriate for designs needing active DDC buffering rather than passive switching. Confirm compatibility with the system's 3.3V power supply voltage and verify that the required equalization and pre-emphasis settings align with the cable and connector specifications.

Specialized Part Context

This part belongs to the PI3VDP1431 family, which includes variants with different DDC channel configurations. The PI3VDP1431AZLSEX specifically incorporates a DDC buffer, whereas the standard PI3VDP1431 uses a passive switch. Both share identical pinouts and electrical characteristics for the TMDS channels, allowing for flexible design choices based on DDC requirements.

Specialized Replacement Considerations

The PI3VDP1431AZLSEX is pin-to-pin compatible with the PI3HDMI511 and PI3HDX511A. Designers should verify that the electrical parameters of these alternative components meet the specific requirements of the target application before substitution.
