4.10 HDMI Interface Bridge
TI’s HDMI transmitter IC Mfr. Part# TFP410-PAP is used for converting the 24-bit RGB video signals from VOUT port of SOC into HDMI output signals. The output of the HDMI transmitter chip terminated to a HDMI connector Mfr. Part# 10029449-001RLF by interfacing suitable filter and ESD circuitry.
Power +5 V is provided to the HDMI connector using current limit load switch TPD12S016PWR for current limiting and overall ESD protection for the HDMI controller. The current limit load switch is controlled by a GPIO expander signal (HDMI_DDC_OE). DDC signals are level translated using standard I2C level translator PCA9306DCT over TPD12S016 for improved drive strength.
