DATA SHEET
DESCRIPTION
The GT4123 and GT4123A are monolithic dual-channel
video multipliers for use in a wide range of applications
including broadcast and multimedia.
Featuring two wideband video inputs and a single control
input, they achieve high quality video mixing of the two
video input signals to a single output by implementing the
function:
V
O
= [ ( V
C
V
A
) + (1 - V
C
) V
B
]
where V
C
is the control input voltage, which may be varied
continuously over the range 0 to 1V with respect to the
ground pin, and V
A
and V
are the video input signals.
The GT4123 operates with typical power supply voltages
of
±
10 volts and draws 15 mA of current. The GT4123A
typically operates from +12 and -5 volt supplies. Both are
available in 8 pin PDIP and 8 pin SOIC.
An Application Note entitled "Using the GT4123 and GT4123A
Video MIxer ICs" (Document No. 520 - 61) is available from
Gennum Corporation.
