APPLICATIONS INFORMATION
General guidance
The ZXFV4583 is a high speed mixed analog/digital
signal processing component requiring the
appropriate care in the layoutofthe application printed
circuit board. A continuous ground plane construction
is preferred.
Suitable power supply decoupling
suggested includes a 100nF leadless ceramic capacitor
close to the power supply connection at pin 14.
In order to avoid coupling between high speed logic
output signals and analog inputs, the test circuit layout
uses connections from the logic output pins routed
away from the analog pins. In the application, similar
care in the layout is required, keeping resistors, R

close to their respective pins, in
particular routing signal CSYNC away from pins 1, 2
and 12.
Evaluation circuit
An evaluation circuit is available, designed to provide
demonstration of the ZXFV4583 function using 50
test instruments. The schematic diagram is shown in
Figure 5 and the printed circuit layout is shown in
Figures 6, 7 and 8.
The circuit includes the Zetex
ZXFV4089DC Restoration Circuit, which is described in
the data sheet for that part. The ZXFV4089 uses the
Back Porch output from the ZXFV4583 in order to
control and stabilize the black level of a video
waveform.
BNC connector sockets allow connection of the
analog video and output to laboratory test
instruments via 50
BNC cables. The circuit can be
adapted for 75
use. The output circuit includes a
resistor matching circuit to present a load of 150
the amplifier and simultaneously provide 50
impedance. The attenuation of this matching circuit is
15.45 dB. As the amplifier is configured for a voltage
gain of 2, the overall gain in a 50
to
output
system is:
6 - 15.45 = -9.45 dB.
Thesynchronizedlogic outputs arebroughtto aheader
for examination using oscilloscope probes. A set of
jumper links allow the selection of operation with or
without the built in color carrier filter. The selection is
depicted on the board itself.
