EIAJ Sound Multiplexing Decoder
CXA2202M
Preliminary
Description
The CXA2202M, 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.
28 pin SOP (Plastic)
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.
Applications
• Color TVs
• Hi-Fi VCRs
