TA1227AP

The TA1227AP detects EDTV2 identification signals.It detects the 27 bits on the 22H and 285H lines of each frame and outputs to the read bus.The methods of detection are following.B1 to B5,and B24 NRZ signal:Y signal level detection at BPF output,B6 to B23 fsc phase modulation signal:converts the IQ demodulation signal of the main signal processing IC to a color difference signal and detects the level..

Features of the TA1227AP are:(1)I2C bus-controllable;(2)Y and I,Q inputs;(3)compatible with sandcastle pulse (VD,HD,and GP) input;(4)auto adjustment of 4/7 fsc BPF f0.

The maximum ratings of the TA1227AP can be summarized as:(1):the characteristic is power supply voltage,the symbol is VCC,therating is 14.0,the unit is V;(2):tthe characteristic is power dissipation,the symbol is PD,therating is 1380,the unit is mW;(3):the characteristic is operating temperature range,the symbol is Topr,therating is -20 to 65,the unit is ;(4):the characteristic is storage temperature range,the symbol is Tstg,therating is -55 to 150,the unit is .When using the device at above Ta=25,decrease the power dissipation by 11.2mW for each increase of 1
