AD722
Key Features
- The AD722 also accepts the subcarrier clock from an external video source
- If available, the AD722 will also accept a standard CSYNC signal by connecting VSYNC to +5 V and applying CSYNC to HSYNC pin
- The AD722 contains decoding logic to identify valid HSYNC pulses for correct burst insertion
- Delays in the U and V chroma filters are matched by an on-chip sampled-data delay line in the Y signal path
- These low-pass filters are optimized for minimum pulse overshoot
- This prepensation delay is already present in TV broadcasts
- The AD722 es in a space-saving SOIC and is specified for the 0°C to +70°C mercial temperature range
