Function

Digital Ground.

Analog Ground.

Digital I/O Supply Voltage (3.3 V).

Digital Core Supply Voltage (1.8 V).

Analog Supply Voltage (3.3 V).

PLL Supply Voltage (1.8 V).

Analog Video Input Channels.

No Connect Pins.

Video Pixel Output Port.

HS is a horizontal synchronization output signal.

VS is a vertical synchronization output signal.

FIELD is a field synchronization output signal.

I2C Port Serial Data Input/Output Pin.

I2C Port Serial Clock Input (Max Clock Rate of 400 kHz).

This pin selects the I2C address for the ADV7189. ALSB set to a Logic 0 sets the address for a

write as 0x40; for ALSB set to a logic high, the address selected is 0x42.

System Reset Input, Active Low. A minimum low reset pulse width of 5 ms is required to reset

the ADV7189 circuitry.

This is a line-locked output clock for the pixel data output by the ADV7189. Nominally 27 MHz,

but varies up or down according to video line length.

This is a divide-by-2 version of the LLC1 output clock for the pixel data output by the ADV7189.

Nominally 13.5 MHz, but varies up or down according to video line length.
