5 / 86 page TA1276AN 2002-03-29 5 PIN No. PIN NAME FUNCTION INTERFACE CIRCUIT INPUT / OUTPUT SIGNAL 6 V / I output Outputs R-Y (V) or Q signal.It includes LPF that can remove carrier. The chroma signal that routed ACC and TOF circuits (before demo input) can be monitored by pulling up this pin at 10kΩ. DC 2.5V Rainbow color bar : 360mVp-p 7 1H DL control Outputs the result of whether the signal is PAL, SECAM or NTSC. Connect the output to the 1H DL IC. In the case of discrimination between white or black, the voltage just before that is retained. The voltage immediately after turning-on is not fixed. 8.4V: PAL 4.3V: SECAM 0V: NTSC 8 9 10 4.43MHz X’tal M PAL X’tal 3.58MHz X’tal Connect X’tal. In the case of series capacity, the oscillation frequency (f0) can be changed. In the case of parallel capacity, the changeable range of frequency can be changed. DC 4.0V 90mVp-p 11 APC filter Connect APC filter demodulating the chroma. The oscillation frequency of VCXO varies depending on the voltage at this pin. DC 12 VCC1 (5V) The VCC of the chroma and I 2 C Bus blocks. Connect 5V (Typ.) ― ― |
