Sync-mix operation
On BH7600AFS, it is necessary to operate sync-mix Y signal and control signal synchronized with the Y signal (SYNC1, SYNC2). Use this control signal, (1) When the Y signal which has no sync is inputted, it is outputted with a sync. (2) When the Y signal which has sync is inputted, it is possible to output as that. Then, please refer to show how to use SYNC1, SYNC2 palse.

● ■ Operation description of each block BH7602FS How to set video input level in DC_SHFT circuit
Technical Note
BH7602FS is build in DC_Shift block and it operate without input coupling capacitor. It is necessary to set input voltage of VREF (7pin) terminal to VIDEO signal input level because of enough output dynamic range.

The relation of V_IN, VREF, V_OUT in this place
V_OUT=0.7+2(V_IN-VREF+0.4)

and the input possible range of VREF is
0.4≦VREF≦1.4 [V]
(eq.2)
It shows the relation of V_IN-V_OUT at each VREF value on Fig.6. On the other hand, the operation range of V_OUT (VIDEO OUTPUT) becomes 0.7V~3.3V (2.6Vp-p) of the circuit composition, and needs to adjust VREF terminal voltage to be kept this range for inputted VIDEO signal. VREF terminal voltage and V_IN input possible range are shown in Fig.5. Caution on use, after confirming Fig.5, adjust VREF terminal voltage.
