General Description
ADV7197 General Description
The ADV7197 is a triple, high-speed, digital-to-analog encoder on a single monolithic chip. It consists of three high-speed video D/A converters with TTL-compatible inputs.
The ADV7197 has three separate 10-bit-wide input ports that accept data in 4:4:4 10-bit YCrCb or RGB, or 4:2:2 10-bit YCrCb. This data is accepted in HDTV format at 74.25 MHz or 74.1758 MHz. For any other high definition standard but SMPTE274M or SMPTE296M, the Async Timing Mode can be used to input data to the ADV7197. For all standards, external horizontal, vertical, and blanking signals or EAV/SAV codes control the insertion of appropriate synchronization signals into the digital data stream and therefore the output signals.
The ADV7197 outputs analog YPrPb HDTV complying to EIA-770.3, or RGB complying to RS-170/RS-343A.
The ADV7197 requires a single 5 V/3.3 V power supply, an optional external 1.235 V reference, and a 74.25 MHz (or 74.1758 MHz) clock.
The ADV7197 is packaged in a 52-lead MQFP package.
