NEC's UPC1663GV is a video amplifier with differential input
and output stages. A high frequency process (f
T
= 6 GHz)
improves AC performance compared with industry-standard
video amplifiers. This device is excellent as a sense amplifier
for high-density CCDs, as a video or pulse amplifier in high-
resolution displays, and in communications equipment.

Attention:
Due to high frequency characteristics, the physical circuit layout is very
critical. Supply voltage line bypass, double-sided printed-circuit board,
and wide-area ground line layout are necessary for stable operation.
Two signal resistors connected to both inputs and two load resistors
connected to both outputs should be balanced for stable operation.
