SYNC Processor, Frequency Counter IC for TV Component Signals
TA1370FG is a sync processor for TV component signals. TA1370FG provides sync and frequency counter processing for external input signals. These functions are integrated in a 30 pin SSOP-type plastic package. TA1370FG provides I2C bus interface, so various functions and controls are adjustable via the bus.

Read Mode
* POR (Power on reset) (0): Status read (at second data read and subsequent) (1): Power on (at first data read) HD-IN (Input signal self-check result) Detects HD or H-SYNC input signal selected by INPUT SW. (0): No signal input (1): Signal input V FREQ DET (Vertical frequency of SYNC or VD input selected by FREQ DET SW) (0000000)(0001100): No-VD (0001101) : Vicinity of 162 Hz (1111111) : Vicinity of 17 Hz How to calculate vertical frequency (X): Convert V-FREQ DET read data into decimal and define the resulting value as Y. Where H-FREQUENCY is 31.5 kHz, Z = 476.2 s Where H-FREQUENCY is 28.125 kHz/33.75 kHz/45 kHz, Z = 474.1 s Vertical frequency (X) = 1 / (Y x Z) [Hz] Error of Y is +1, -0. If vertical frequency is 162 Hz or more, the frequency cannot be accurately measured. Time constant used to separate V.SYNC from integrated C.SYNC is 9 s (error: 1 s). H FREQ DET (Horizontal frequency of SYNC or HD input selected by FREQ DET SW) (0000000): No signal input (1111111): 53 kHz or more How to calculate horizontal frequency (X): X, Y, and Z are defined same as for V FREQ. Horizontal frequency (X) = Y / (5 x Z) [kHz] Error of Y is +1, -0. If horizontal frequency is 53 kHz or more, the frequency cannot be accurately measured. When V-SYNC or VD is not input, horizontal frequency cannot be measured, resulting in data = (0000000). Note 1: The start trigger for frequency counting is the internal reset-pulse made from ACK of 2nd byte in BUS read mode. The counting period is between the first V-sync (VD) and the second V-sync (VD) after the trigger. The counted data will have +1 or -0 error according to the read timing. To assume stable data reading; 1. Set BUS reading interval more than 3 V. 2. Don't use the first data because it is unsettled. are recommended. Note 2: Ignore data (H FREQUENCY DET, V FREQUENCY DET) = (0000001, 0001101). This data is obtained when the pin voltage of SYNC-IN pin is higher than sync separation level and when any signal is not inputted into SYNC-IN pin.

Application Circuit 2 (How to measure H/V frequency)
To measure H/V frequency of signal 2 (fH2: unknown) correctly, use two separated input terminals as the following figure. 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 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.
