CXA2013M
EIAJ Sound Multiplexing Decoder
Description
The CXA2013M 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), volume, tone control and
muting.
Features
•
Adjustment free of filter
•
Audio multiplexing decoder
•
Sound processor
— One external input
— Bass control
— Treble control
— Volume control
— Balance control
are all included in a single chip. Almost any sort of
signal processing is possible through this IC.
•
Separation adjustment, each mode control and sound
processor control are possible through I
2
C BUS.
