ADV7189B

The ADV7189B 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-, and 8-bit CCIR601/CCIR656.

The advanced and highly flexible digital output interface enables performance video decoding and conversion in linelocked,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 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 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 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 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 ±5% line length variation.

The output control signals allow glueless interface connections in almost any application. The ADV7189B modes are set up over a 2-wire, serial, bidirectional port (I2C-compatible).

The ADV7189B is fabricated in a 3.3 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7189B is packaged in a small, 80-lead LQFP Pb-free package.
