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.
