CXA2202N
24 pin SSOP (Plastic)
EIAJ Sound Multiplexing Decoder
Description
The CXA2202N, is a bipolar IC designed as EIAJ
TV sound multiplexing decoder, provides various
f u n c t i o n s i n c l u d i n g s o u n d mu l t i p l ex i n g
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
