Rohm BH7600AFS Wide band 3-output video driver Datasheet

High-performance System Video Driver Series
Wide Band 3-output
Video Driver
No.09065EAT05
BH7600AFS, BH7601FS, BH7602FS
●
Description
BH7600AFS, BH7601FS and BH7602FS is wide band 3-output video driver for high-definition television system. This video
driver is built in the DC output circuits (LINE1, LINE2, LINE3 output ) for D terminal and detector to connect. And they have
line-up build in sync-mix, DC shift input, selectable LPF every applications.
●
Features
1) Built-in the DC output circuits (LINE1, LINE2, LINE3) / detector to connect.
2) Built-in OUTPUT MUTE circuit
2
3) I C BUS control
4) Pedestal clamp input with sync mix (BH7600AFS)
5) Sync tip clamp input 1ch, bias input 2ch (BH7601FS)
6) Possible to be directly connected with DAC by DC shift circuit (BH7602FS)
7) Built-in power down function (BH7602FS)
●
Applications
DVD Player, DVD Recorder, DVC, DSC, STB, TV and so on.

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.
(1) When the Y signal which has no sync is inputted

( ii ) 2 value sync mix

How to set video input level in DC_SHFT circuit
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)
（eq.1）
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.
