TA1275AZ

The TA1275AZ is a type of SECAM demodulation IC, which accomplishes a multicolor system with TB1231 series. This IC requires vety few external parts.

Features of TA1275AZ are:(1)working with TB1231 series, which is pal/ntsc/ pif/vif/video/chroma/def processor; (2)built-in bell filter; (3)built in FM demodilator with pll circuit for color demodulation and SECAM identification; (4)DC volt age offset of demodulated signal adjuster; (5)input terminal for external R-Y/B-Y signal.

The absolute maximum ratings and recommended conditions of the TA1275AZ can be summarized as: (1)supply volta ge: 8V; (2)signal voltage at each input pin: 5Vp-p; (3)power consumption: 780mW;(4)power sonsumption reduction ratio: 6.3mW/; (5)operating temperature:-20 to 65; (6)storage temperature:-55 to 150. Recommended conditions: supply voltage(pin9, 8): 4.5min, 5.5typ and 5.5 max; (2)Y input signal level(white: 100%, including sync): 0.9Vp-p min, 1.0Vp-p typ and 1.1Vp-p max; (3)color difference input level(bust level): 270mVp-p min, 300mVp-p typ and 330mVp-p max; SCP input level(G level): 3.25V min, 4.0V typ and 5.0V max.
