TA1370FG
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 I
2
C bus interface, so various functions and
controls are adjustable via the bus.

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 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 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: 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.

Decision algorithm (detection range, detection times and so on) should be determined under
consideration of Note 1, Note 2 and the other factors such as signal strength, existence of ghost signal,

At the moment of the first acknowledge, the master transmitter becomes a master receiver and the slave
transmitter. This acknowledge is still generated by this slave.
The Stop condition is generated by the master.

otherwise the IICBUS may cause error.
Optional Data Transmit Format: Automatic Increment Mode
In this transmission method, data is set on automatically incremented sub-address from the specified

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.

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, I

C BUS data
