CXA2202N

CXA2202N EIAJ Sound Multiplexing Decoder Description The CXA2202N, 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) Internal filter eliminates interference from digital facsimile signals The discrimination time needed to shift from multiplexing sound to monaural sound is reduced. Output level: 520mVrms (1kHz, monaural, 100%) Forced monaural mode can be set to operate only for stereo broadcasts or for stereo/bilingual broadcasts.
