GENERAL DESCRIPTION

video signal peak-to-peak range of 0.5 V to 1.6 V. Alternatively,

these can be bypassed for manual settings.

The ADV7181B 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 16-/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 ADV7181B 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 ADV7181B is fabricated in a 3.3 V CMOS process. Its

monolithic CMOS construction ensures greater functionality

with lower power dissipation.

The 6 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

The ADV7181B is packaged in a small 80-lead LQFP Pb-free

package.
