It consists of three high speed, 8-bit video DACs with plementary outputs, a standard TTL input interface, and a high impedance, analog output current source. The ADV7125 has three separate 8-bit-wide input ports. A single +5 V/+3.3 V power supply and clock are all that are required to make the device functional. The ADV7125 has additional video control signals, posite SYNC and BLANK, as well as a power save mode.
