GENERAL DESCRIPTION

video signal peak-to-peak range of 0.5 V up to 1.6 V.

Alternatively, these can be bypassed for manual settings.

The ADV7189 integrated video decoder automatically detects

and converts a standard analog baseband television signal

compatible with worldwide standards NTSC, PAL, and SECAM

into 4:2:2 component video data compatible with 20-/16-/10-/

8-bit CCIR601/CCIR656.

The fixed 54 MHz clocking of the ADCs and datapath for all

modes allows 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 5ꢀ 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

compatible).

The advanced and highly flexible digital output interface

enables performance video decoding and conversion in line-

locked clock based systems. This makes the device ideally suited

for a broad range of applications with diverse analog video

characteristics, including tape based sources, broadcast sources,

security/surveillance cameras, and professional systems.

The ADV7189 is fabricated in a 3.3 V CMOS process. Its

monolithic CMOS construction ensures greater functionality

with lower power dissipation.

The 12-bit accurate A/D conversion provides professional

quality video performance and is unmatched. This allows true

10-bit resolution in the 10-bit output mode.

The ADV7189 is packaged in a small 80-lead LQFP Pb-free

package.

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 input
