Function

Digital ground for the I/O

Reference clock for input pixel data.

The clock frequency is 27.0 MHz

I2C slave address setting.

“Low” is for the address of 40h, “High” is for the address of 42h.

Horizontal sync signal input or output.

It is an input and output in the slave and master mode, respectively.

Vertical sync input or output. Or Odd Even signal output.

It is an input and output in the slave and master mode, respectively.

Video data outputs.

In the Y/U/V output mode, the output is the 10-bit digital luma signal with a

composite sync.

VD9 is MSB and VD0 is LSB.
