3-CHANNEL VIDEO PREAMPLIFIER PROVIDED WITH OSD MIX

AND RETRACE LINE BLK FOR HIGH-RESOLUTION

• OSD display period overlapped with clamping pulse period will

cause abnormal operation. As measures against this, external

circuit as given in the following diagram is recommended:

4) Retrace line BLK input pins

• Input formula is open.

(See page 2-1110.)

• Threshold voltage is 1.5V.

• Ensure that input pin is grounded when no retrace line BLK func-

tion is used.

5) Main, Sub OSD adjustment pins

• Use within the range of 0V-5V.

• Control characteristics are as given in the following drawing:

• Open if main OSD adjustment or sub OSD adjustment is not

used.

• If, in application, wiring on the substrate causes interference

wave to get into these pins, affecting even IC input, consider

addition of such as bus controller.

• Ensure that main, sub OSD adjustment pins are open or

grounded when no OSD Mix function is used.

PRECAUTIONS FOR APPLICATION

• Wire output pins to output pulldown resistors at a shortest dis-

tance.

• Voltage in the IC output signal pedestal area is recommended for

use at about 2V.
