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

=5 V)

· The pin configuration of the CXA1518S is identical

to that of the CXA1138AS.

Applications

· Color TVs

· Hi-Fi VCRs

· Liquid crystal TVs

Description of Operation

Pin numbers in brackets are for the CXA1518Q.

The sound multiplexing signal input from Pin 6 (Pin 3) passes through IN AMP, and is added to the Cue BPF,
SUB BPF and the MAIN de-emphasis circuits.

Discrimination system
The Cue BPF passes only the Cue signal component of the multiplexing signal. The AM demodulator
detects the amplitude modulation of the Cue signal (AM wave) and generates a sine wave of either 922.5
Hz (for bilingual) or 982.5 Hz (for stereo sound).
COMP shapes the carrier-stripped Cue signal into a waveform, transforming it into pulses of either 922.5
Hz or 982.5 Hz, after which it is added to the LOGIC unit.
A 3.5f

VCO generates a 3.5f

pulse locked to the Cue signal carrier wave (3.5f

), and sends it to the

LOGIC unit.
The LOGIC unit performs broadcast mode discrimination using the countdown method. From this result,
and the existence/absence of a SUB signal from the SUB Detector, MUTE ON/OFF from CONT, MODE
Switch, and the FOMO ON/OFF commands, the logic unit generates an output switchover control signal to
control the output statuses of OUTPUT SW and MAIN OUT.

--15--

CXA1518Q/S

Main system
MAIN DEEM applies de-emphasis on the MAIN signal component and removes the SUB and Cue
components. After having passed through MAIN DEEM, the MAIN signal is added to MARTIX, OUTPUT
AMP, and MAIN OUT.

Sub system
SUB BPF passes the SUB signal component of the multiplexed signal. A 4.5f

trap filter then removes the

digital facsimile signal component.
FM demodulation frequency demodulates the Sub signal.
The SUB DEEM applies de-emphasis on the FM demodulated Sub signal and removes the carrier wave
component.
After passing through SUB DEEM, the SUB signal is added to MATRIX and OUTPUT AMP.

Matrix and output system
When broadcasting in stereo, MATRIX generates L and R signals by adding and subtracting the MAIN
signal from MAIN DEEM and the SUB signal from SUB DEEM.
OUTPUT AMP & OUTPUT SW switch the output signals as instructed by LOCIG. Note that MAIN OUT
always outputs the MAIN signal component regardless of the broadcast mode.

Adjustment Methods
