Video Rate Codec
ADV7202
GENERAL DESCRIPTION
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 54 MHz.
It also has up to eight auxiliary inputs that can be sampled by
an 843 kHz SAR ADC for system monitoring, etc.
The back end consists of four 10-bit DACs that run at up to
54 MHz and can be used to output CVBS, S-Video, Component
YCrCb, and RGB.
This Codec also supports Picture-on-Picture with the 3-channel
I/P mux that also muxes to the DAC O/Ps.
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.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADV7202 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
