Triple SCART A/V Switch

August 2000

FEATURES

DESCRIPTION

The AVPro^®5003 is a low cost IC that performs

switching of analog audio and video signals. The

device accepts analog audio and video inputs from

three external sources, typically a video encoder

IC/stereo DAC, an auxiliary SCART connector, and

a VCR SCART connector. The input signals from

these sources are presented to a set of internal

multiplexers that perform the SCART switching

function. Outputs are provided to the VCR and

auxiliary SCART connectors, as well as a TV

SCART connector and an RF modulator. Video

outputs are buffered to drive 150 Ω loads. Audio

outputs are buffered to provide 2 Vrms output into

600 ohms. Typical applications for the 5003 include

digital video recorders (DVRs) and digital receivers

for satellite, cable, and terrestrial television.

• SCART connections for TV, VCR, AUX

• Integrated video drivers

• Integrated audio drivers

- Negative supply eliminates AC coupling

caps

• 5-bit audio attenuation for TV output

- Attenuation from 0 to 31 dB, 1 dB steps

- Mute of TV outputs

• Serial port control of SCART switching

• 64-lead MQFP packaging (JEDEC MO-108)
