EIAJ Sound Multiplexing Decoder
CXA2202N
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.
24 pin SSOP (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
