GENERAL DESCRIPTION
The ADV7123-EP is a triple, high speed digital-to-analog
converter (DAC) on a single monolithic chip. It consists of three
high speed, 10-bit video DACs with complementary outputs,
a standard TTL input interface, and a high impedance, analog
output current source.
The ADV7123-EP has three separate 10-bit-wide input ports.
A single 3.3 V power supply and clock are the only components
required to make the part functional. The ADV7123-EP has
additional video control signals: composite SYNC and BLANK.
The ADV7123-EP also has a power save mode.
The ADV7123-EP is fabricated in a 5 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with lower power dissipation. The ADV7123-EP is available
in a 48-lead LFCSP package.
Full details about this enhanced product are available in the
data sheet, which should be consulted in conjunction
with this data sheet.
