TDA4481-D
Overview
This circuit configuration permits high-quality processing of audio carriers for all standards, providing separate inputs for the video and audio carriers. The audio carrier signal (FM or AM) is passed to two multiplying mixer arrangements via a 3-stage variable wide-band amplifier with levelled output signals.
- High signal sensitivity
- High signal to noise ratio
- Easy alignment of the multistandard filters
- Converter for different intercarrier frequencies
- AF output level matched to SIMAVELEC condition
- Few external components
- Alignment free AM demodulator for standard L
- Standardized SCART interface
- Standard-, SCART- and Mute-switch TTL compatible
- AF attenuator
