8.15. HDMI Interface
The video output of the Snowball board is available on the HDMI connector. The HDMI output is
provided by the AV8100 which is a low power combo video HDMI and CVBS transmitter. The DSI
digital input interface of the AV8100 is interfaced on one of three MIPI DSI (MIPI-DSI2) offered by
the A9500 processor.
Figure 8.19 illustrates the HDMI interface design

8.15.1. Processor MIPI-DSI Interface
The main driver for the HDMI interface originates at the processor via the DSI2 bus. The A9500
provides the signals (1 clock lane and 2 data lanes) on the DSI2 bus used by the AV8100HDMI
transmitter chip. There are four signals used to control the HDMI transmitter that originate at
the processor. These are I2C0_SDA, I2C0_SCL, GPIO_192 (HDTV_INTn signal) and GPIO_196
(HDTV_RST signal).
