PI3HDX511DZLE+DAX

Specialized Overview

The PI3HDX511DZLE+DAX is a low-power HDMI 1.4b compliant redriver with 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 an integrated DDC level shifter, automatic output squelch, and HPD function for power management. Powered by a single 3.3V supply, it offers ESD protection of 8kV contact and HBM. The component is housed in a compact 30-pin QFN (ZL30) package measuring 2.5 x 4.5 mm.
