CXA1518Q/S
EIAJ Sound Multiplexing Decoder
Description
The CXA1518Q/S are bipolar ICs designed for
EIAJ TV sound multiplexing decoders. These ICs
provide various functions including sound
multiplexing demodulation, broadcast mode
discrimination (stereo/bilingual discrimination
display), mode display, and muting.
Features
•
External parts greatly reduced with a built-in active
filter.
•
Count down can be used for broadcast mode
discrimination so that adjustment for discrimination
system (Q-OSC) is not required.
•
Output level of 380 mVrms (1 kHz, MONO, 100 %)
•
Forced monaural operates with both stereo and
bilingual broadcasts.
•
Built-in digital facsimile interference elimination
filter.
•
Low supply voltage (V
CC
=5 V)
•
The pin configuration of the CXA1518S is identical
to that of the CXA1138AS.
