Video Sync Pulse Remover Application
All CMOS Analog to Digital Converters (ADs)
have a parasitic latch-up problem when subjected
to negative input voltage levels Since the sync
tip contains no useful video information and it is
a negative going pulse
we can chop it off
Figure 7 shows a unity gain connected amplifier
A of an EL2257C Figure 8 shows the complete
input video signal applied at the input as well as
the output signal with the negative going sync
pulse removed

Multiplexing with the EL2257CEL2357C
The ENABLE pins on the EL2257CEL2357C
allow for multiplexing applications
Figure 9
shows an EL2357C with all 3 outputs tied togeth-
er driving a back terminated 75
X video load
Three sinewaves of varying amplitudes and fre-
quencies are applied to the three inputs Logic
signals are applied to each of the ENABLE pins
to cycle through turning each of the amplifiers
on one at a time Figure 10 shows the resulting
output waveform at VOUT Switching is complete
