input video signal peak-to-peak range of 0.5 V to 1.6 V.
Alternatively, these can be bypassed for manual settings.
The fixed 54 MHz clocking of the ADCs and datapath for all
modes allow very precise, accurate sampling and digital
filtering. The line-locked clock output allows the output data
rate, timing signals, and output clock signals to be synchronous,
asynchronous, or line-locked even with ±5% line length
variation. The output control signals allow glueless interface
connections in almost any application. The ADV7189 modes
are set up over a 2-wire, serial, bidirectional port (I²C-
security/surveillance cameras, and professional systems.
compatible).
The 12-bit accurate A/D conversion provides unmatched
professional quality video performance. This allows true 10-bit
resolution in the 10-bit output mode.
The ADV7189 is fabricated in a 3.3 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with lower power dissipation.
The 12 analog input channels accept standard Composite,
S-Video, YPrPb video signals in an extensive number of
combinations. AGC and clamp restore circuitry allow an
The ADV7189 is packaged in a small 80-lead LQFP Pb-free
package.
