This data brief introduces the STV6419 low-cost audio/video switch and 4-channel SD video filter product features, applications and design guidelines.
The STV6419 is a highly integrated circuit designed for switching, filtering, and buffering audio and video signals in dual, non-full SCART applications. It is optimized for use in digital set-top boxes or DVD recorders, particularly for European markets.
The device provides routing for CVBS and RGB signals between inputs such as MPEG decoders and VCRs to TV and VCR outputs. It features 7-MHz low-pass filters on encoder inputs, integrated output buffers capable of driving standard video loads, and an audio section supporting stereo sound with selectable gain up to +28 dB.
