PI3HDX511DZLEX

Specialized Overview

The PI3HDX511DZLEX is a low-power HDMI 1.4b compliant redriver with an integrated DisplayPort dual-mode level shifter, designed for ultra-mobile applications. It operates up to 3.4 Gbps per lane and supports 4K Ultra HD, 3D video formats, and 48-bit Deep Color. The device features flexible six-step equalization (2.5, 5, 7.5 dB) and three-step pre-emphasis control (0, 1.5, 2.5 dB). It includes automatic output squelch and HPD functions for power saving, an integrated DDC level shifter, and 3.3V single supply operation. ESD protection is rated at 8kV contact and 8kV HBM. It is housed in a compact 30-pin QFN (ZL30) package measuring 2.5 x 4.5 mm.

Specialized Procurement Notes

Verify the component against the official Diodes Incorporated datasheet to confirm pinout compatibility and electrical specifications. Ensure the 30-pin QFN footprint matches the design layout. Confirm that the 3.3V supply voltage and ESD ratings meet system requirements before finalizing procurement.

Specialized Selection Notes

Select this component when space constraints require a small 2.5 x 4.5 mm package. It is suitable for designs needing DP dual-mode support alongside HDMI redriver functionality. Consider its low standby current for battery-operated devices requiring efficient power states management.

Specialized Part Context

This part belongs to the PI3HDX511 series of video interface ICs from Diodes Incorporated. It specifically addresses the need for signal conditioning in tight spaces within mobile computing platforms. The ZLEX suffix indicates the specific tape and reel packaging configuration for surface mount assembly.

Specialized Replacement Considerations

Check for direct substitutes within the PI3HDX511 family, such as variants with different package sizes or thermal characteristics. Verify functional equivalence regarding equalization steps and power consumption if replacing with other HDMI redriver models.
