One is for frequency measuring (SYNC2-in) and the other is for the AFC (SYNC1-IN). And measure H/V frequency of signal 2 (fH2: unknown) on condition that AFC is stable (AFC locks in signal 1 (fH1: known).) or that AFC is free-run when SYNC1-IN is no-signal. Signal 1 (fH1: known) Signal 2 (fH2: unknown) Signal 1 AFC SYNC1-IN for H-AFC BUS READ Internal pulse (A) H/V FREQ COUNTER Signal 2 SYNC2-IN for H/V freq. counter TA1370FG This IC’s H/V frequency counting is done by internal pulse (A) which is made in AFC circuit. So, if AFC circuit doesn’t lock in the regular frequency, the frequency of pulse (A) will not be correct and the H/V frequency data will not be showed correct data. Decision algorithm of H/V frequency detection (detection range, detection times and so on) should be determined under consideration the factors such as signal strength, existence of ghost signal, H-AFC stability, I2C BUS data transmission and so on via prototype TV set evaluation. 40 2005-09-05 TA1370FG Package Dimensions Weight: 0.63 g (typ.) 41 2005-09-05 TA1370FG 42 2005-09-05
