Key Features
- Selectable Cutoff Frequencies: The sixth-order video filters have cutoff frequencies ranging from 9 MHz to 36 MHz, selectable by two logic pins for RGB, high definition, and standard definition video signals.
- Multiplexed Inputs: 2:1 multiplexers on all video inputs, useful for filtering multiple sources of video signals.
- Adjustable Gain and Offset: Throughput filter gain can be selected to be ×2 or ×4, and output voltage offset is continuously adjustable over an input-referred range of ±500 mV.
- Rail-to-Rail Output: Output buffers can drive two 75 Ω terminated loads, either dc-coupled or ac-coupled, with rail-to-rail output capabilities.
- Low Power Consumption: Single-supply operation and a disable feature that reduces supply current to 15 μA when not in use.
- Compact Packaging: Available in a 24-lead QSOP package.
Applications
- Set-top boxes
- Personal video recorders
- DVD players and recorders
- HDTVs
- Projectors
