Multiformat SDTV Video Decoder
The ADV7181B integrated video decoder automatically detects and converts a standard analog baseband television signalcompatible with worldwide standards NTSC, PAL, and SECAM into 4:2:2 component video data-compatible with 16-/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 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 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 ADV7181B modes are set up over a 2-wire, serial, bidirectional port (I2C compatible).
The ADV7181B is fabricated in a 3.3 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation.
The ADV7181B is packaged in a small 80-lead LQFP Pb-free package.
