TPD12S016 Value-Line HDMI Companion Chip

Texas Instruments' TPD12S016 is a single-chip HDMI interface device with auto-direction sensing I2C voltage level shift buffers, load switch, and integrated high-speed ESD protection clamps. The device pin mapping matches the HDMI Type D connector with four differential pairs. This device offers eight low-capacitance ESD clamps, allowing HDMI 1.4 data rates. The integrated ESD circuits provide good matching between each differential signal pair, which allows an advantage over discrete ESD solutions where variations between ESD protection clamps degrade the differential signal quality. The TPD12S016 provides a current limited 5 V output for sourcing the HDMI power line. The current limited 5 V output supplies up to 55 mA to the HDMI receiver.
