28 pin SOP (Plastic)
Preliminary
EIAJ Sound Multiplexing Decoder
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.
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
