STV6419 Low-cost audio/video switch and 4-channel SD video filter
The STV6419 is a highly integrated I²C bus-controlled audio and video switch matrix, optimized for use in digital set-top box or DVD recorder applications. It provides the audio and video routings (CVBS and RGB) required in a non-full two SCART set-top box design.
The STV6419 is a fully integrated solution for filtering and buffering SD signals.
技术特性
- I²C bus control
- Interrupt signal output
- Video section:
- Three CVBS inputs; two CVBS outputs
- Two RGB or YPrPb or chroma / one FB input; one RGB or YPrPb or chroma / one FB output
- 7-MHz low-pass filters on four encoder inputs
- Gain of 6 dB on all RGB and CVBS outputs
- Capabilities of integrated output buffers:– CVBS_TV can drive two standard 150-Ω video loads – CVBS_VCR can drive one standard 150-Ω video load and one 600-Ω modulator load – RGB can drive a standard 150-Ω video load
- AC- or DC-coupled video outputs
- Two slow blanking inputs/outputs
- Bottom clamp on all CVBS and bottom/average/synchronized clamp on RGB inputs
- AC-coupled inputs for all video signal
- Audio section:
- Three inputs; two outputs
- Differential or single-ended audio encoder input
- Selectable gain on one stereo input
- Audio muting on the output
- Audio outputs drive 3.1 V RMS into 2 kΩ
- Full-range volume control with soft control
- Applications
- Set-top boxes (IP, cable, satellite, terrestrial)
- Integrated digital TV plug-in
