The ADV7202 is a video rate sampling codec. It has the capability of sampling up to five NTSC/PAL/SECAM video I/P signals. The resolution on the front end digitizer is 12 bits; 2 bits (12 dB) are used for gain and offset adjustment. The digitizer has a conversion rate of up to 54 MHz. The ADV7202 can have up to eight auxiliary inputs that can be sampled by an 843 kHz SAR ADC for system monitoring. The back end consists of four 10-bit DACs that run at up to 200 MHz and can be used to output CVBS, S-Video, Component YCrCb, and RGB. This codec also supports Picture-on-Picture. The ADV7202 can operate at 3.3 V or 5 V. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7202 is packaged in a small 64-lead LQFP package.
