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
  • Integrated 150-Ω buffers
  • 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
  • Crosstalk: 50 dB minimum
• Audio section:
  • Three inputs; two outputs
  • Stereo sound capability
