ADV7184BSTZ

The ADV7184 integrated video decoder automatically detects and converts standard analog baseband television signals compatible with worldwide NTSC, PAL, and SECAM standards into 4:2:2 component video data compatible with 16- or 8-bit CCIR 601/CCIR 656.The advanced, 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 and surveillance cameras, and professional systems.The accurate 10-bit ADC provides professional quality video performance and is unmatched. This allows true 8-bit resolution in the 8-bit output mode.The 12 analog input channels accept standard composite, S-video, and component 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% variation in line length. The output control signals allow glueless interface connections in most applications. The ADV7184 modes are set up over a 2-wire, serial, bidirectional port (I2C compatible).SCART and overlay functionality are enabled by the ability of the ADV7184 to process CVBS and standard definition RGB signals simultaneously. Signal mixing is controlled by the fast blank pin. The ADV7184 is fabricated in a 3.3 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. It is packaged in a small, Pb-free, 80-lead LQFP.Applications High end DVD recorders Video projectors HDD-based PVRs/DVDRs LCD TVs Set-top boxes Security systems Digital televisions AVR receivers
