Description
Ground for Digital Supply.
Digital I/O Supply Voltage (1.8 V to 3.3 V).
Digital Supply Voltage (1.8 V).
Video Pixel Output Port.
This pin should be connected to the 28.6363 MHz crystal or not connected if an external
1.8 V, 28.6363 MHz clock oscillator source is used to clock the ADV7182. In crystal mode, the
crystal must be a fundamental crystal.
Input Pin for the 28.6363 MHz Crystal. This pin can be overdriven by an external 1.8 V,
28.6363 MHz clock oscillator source. In crystal mode, the crystal must be a fundamental crystal.
PLL Supply Voltage (1.8 V).

O
Interrupt Request Output. Interrupt occurs when certain signals are detected on the input video.
I
System Reset Input. Active low. A minimum low reset pulse width of 5 ms is required to
reset the ADV7182 circuitry.
I
This pin selects the I2C address for the ADV7182. For ALSB set to Logic 0, the address
selected for a write is 0x40; for ALSB set to Logic 1, the address selected is 0x42.
I/O I2C Port Serial Data Input/Output Pin.
I
I2C Port Serial Clock Input. The maximum clock rate is 400 kHz.
