EL2030C
120 MHz Current Feedback Amplifier
Video Applications
Contd
Video signals are 1V peak-peak in amplitude
from sync tip to peak white There are 100 IRE
(0714V) of picture (from black to peak white of
the transmitted signal) and 40 IRE (0286V) of
sync in a composite video signal (140 IRE e 1V)
For video applications where a gain of two is
used (double termination) the output of the vid-
eo amplifier will be a maximum of 2V peak-peak
With g5V power supply the EL2030 output
swing of 35V is sufficient to satisfy the video
output swing requirements
The EL2030 can
drive two double terminated coax cables under
these conditions With g15V supplies driving
four double terminated cables is feasible
Although the EL2030’s video characteristics (dif-
ferential gain and phase) are impressive with
g
5V supplies at NTSC and PAL frequencies it
can be optimized when the supplies are increased
to g15V especially at 30 MHz HDTV applica-
tions This is primarily due to a reduction in in-
ternal parasitic junction capacitance with in-
creased power supply voltage
The following table summarizes the behavior of
the EL2030 at g5V and g15V for NTSC In ad-
dition 30 MHz HDTV data is included Refer to
the differential gain and phase typical perform-
ance curves for more data
