Video and audio input connector

2.1

Video input (MIPI DSI) signals

4-lane MIPI DSI signals are connected on DSI to HDMI adapter board as video input

interface. This board supports 2-, 3- or 4-lane DSI video input data and each running up to

800 Mbps.

DSI interface is compatible with DPHY V.0.90 and DSI V.1.02 and Supports inputs of 16-bit

RGB 4:4:4, 24-bit RGB 4:4:4 and 30-bit RGB 4:4:4.

2.2

Audio input (S/PDIF & I2S) signals

S/PDIF or I2S audio input interface is implemented on CN1. DSI to HDMI adapter board

supports standard S/PDIF for stereo LPCM or compressed audio up to 192 kHz, or 2-

channel uncompressed LPCM I2S audio up to 192 kHz.

2.3

Control signals

I2C bus on CN1 serves as the serial port data I/O slave for register access. The default

address is 0x7A.

Reset signal from mother board is connected to Power Down (PD) pin on ADV7533. It is

internal pulled up by ADV7533.

Interrupt output signal is for mother board and it is pull up on DSI to HDMI adapter board.
