PI3HDX511F is a low power HDMI 1.4b ReDriver and Display- Port dual mode level shifter supporting 3.4Gbps data rate with 48-bpp Deep Color support.

For mobile platforms, extending battery hours have been one of the most challenges. PI3HDX511F has rich power saving states management features to extend battery hours less than 1mA stand-by current, passive-type DDC switch, output squelch, HPD (Hot plug Detect) detection and dual power supply (1.5/3.3V) option.

PI3HDX511F also designed to support both source and sink side system application. For dual side application, it supports wide range EQ setting, data/clock pin swapping, double termination/ open-drain output and DDC buffer options.

Main applications are computers, display monitors and related peripheral devices.
