Special Features
MULTIPLEXED VIDEO SIGNAL INPUT
The LM2457 accepts the multiplexed video signal from the
LM1253 which contains the video signal and DC clamp level.
This multiplexed signal is shown in
Figure 3. It was designed
to simplify the interface between the pre-amp and CRT
Driver. Slightly over 1V of dynamic range is provided for the
video and OSD portions of the waveform. The clamp signal
control voltage range is approximately 0.9V. The typical
numbers for the black and white levels shown correspond to
a nominal swing of 40V
P-P at the video outputs of the
LM2457.
