CXA2020M/S
EIAJ Sound Multiplexing Decoder
Description The CXA2020M/S, is a bipolar IC designed as EIAJ TV sound multiplexing decoder, provides various functions including sound multiplexing demodulation, broadcast mode identification (stereo/bilingual discrimination display), mode display, and muting. Features
- Adjustment free of filter.
- High frequency stereo separation improved.
- An internal active filter greatly reduces the external parts.
- Use of the countdown method for broadcast mode identification eliminates the necessity of adjusting the identification system (Cue oscillator).
- Output level: 520m Vrms (1k Hz, monaural, 100%).
- Internal filter eliminates interference from digital facsimile signals.
- The discrimination time needed to shift from multiplexing sound to monaural sound is reduced.
- Forced monaural mode can be set to operate only for stereo broadcasts or for stereo/bilingual broadcasts. Applications
- Color TVs
- Hi-Fi VCRs Structure Bipolar silicon monolithic IC Pin Configuration
