JPN MTS (Multi Channel Television Sound) Decoder IC
http://onsemi.com
Features
•
With SIF circuit, alignment-free* STEREO channel separation.
* In base band signal input mode, separation is adjusted by input level.
•
Three I
2
C slave-addresses are prepared.
•
The maximum output level is as large as 4.2dBV.
(Frequency = 1kHz, distortion = less than 3%, VCC = 5V, TYP)
•
The external clock is unnecessary.
•
A couple of external input terminal is prepared.
Functions
•
Stereo & Bilingual demodulation.
•
Stereo & Bilingual detection.
•
Just clock out.

The value of (1*), (2*), and (3*) affects sensitivity for signal detection. It must be adjusted depending on the
circumstances by the user.
(1*): Recommended constant value 0.0033μF + 470kΩ
(values when tested)
(2*): Recommended matching resistor value R1=1kΩ, R2=1kΩ
Recommended BPF Murata SFSRA4M50DF00-B0
(3*): Recommended constant value 4.7μF to 10kΩ
The ceramic capacitor may be used for the electrolytic capacitor.
