Sony CXA2013M Datasheet

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 — V olume 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 I2C BUS.
