2.10 HDMI Display Interface

The DSS (Display Sub system) interface from AM62X 17x17 SoC is used on the SK EVM to provide a HDMI Interface through a standard Type-A Connector. The SK EVM features a SiI9022A HDMI Transmitter from Lattice semiconductors to convert the 24bit Parallel RGB DSS output stream as well as a McASP to a HDMI-compliant digital audio and video signal. The Data mapping format used is RGB888. The data bus width is 24-bits. SoC_I2C1 is connected to the HDMI Transmitter accesses the compatible mode registers, the TPI registers, and the CPI registers. To use the SiI9022A, the SoC needs to setup the device. This is done through the I2C interface between the SoC and the SiI9022A. Audio Data is sent from SoC to HDMI transmitter through the McASP1 instance. HDMI_I2C Bus accesses the EDID and HDCP data on an attached sink device. TMDS Differential data pairs along with the differential clock signals from the transmitter are connected to the HDMI connector through HDMI ESD device (manufacturer part number TPD12S016PWR), which also acts as a load switch to limit current supplied to the HDMI connector from board 5V supply. The HDMI Framer is powered using 3.3V board IO supply and 1.2V by a dedicated PMIC LDO.
