TA1275BFNG
SECAM Demodulator Processor
TA1275BFNG
The TA1275BFNG is a SECAM demodulation IC, used in
combination with the TB1309 series to achieve a multicolor system.
This IC requires very few external parts.
Features
Combines with the TB1309 series, which is a video processor,
timing controller, and PWM pulse processor for analog LCDs
Built-in bell filter
Built-in FM demodulator with PLL circuit for color demodulation
and SECAM identification
DC voltage offset for demodulated signal adjuster
Input terminals for external R-Y / B-Y signals

16 EXT. B-Y IN
The input pin for the external B-Y
signal. The gain of the internal
amplifier is 0 dB.

17 N.C. (No Connection) Connect to GND.
18 GND
The GND pin.
19 f0-ADJ. FILTER
The pin for connecting a
capacitor for the automatic
adjustment circuit.
Too large a capacitor causes a
time delay obtaining a color
signal on the picture. Yet picture
noise and flickeringoccur if the
capacitor is too small.
