4:1 HIGH SPEED MULTIPLEXER
ZXFV301
DEVICE DESCRIPTION
FEATURES AND BENEFITS
The ZXFV301 is a 4:1 high speed analog switch
designed for use as a buffered video multiplexer and
other high-speed applications.
It features low different gain and phase distortion. The
high speed high output current capability provides 75
cable drive for use in high performance video
applications.
The input channel is selected by means of four logic
lines. An output enable line allows expansion to eight
channels using two devices ZXFV301 as shown in the
example application figure 1.
An alternative device, ZXFV302 has a seperate
datasheet and provides the same functionality and
pin-out as the ZXFV301 but with only two logic lines
controlling the switch via a decoder.

APPLICATIONS INFORMATION
Introduction
A typical circuit application is outlined in Figure 1,
above, where two devices are combined to provide
8-to-1 multiplexing. A more detailed basic application
circuit for 4 dc-coupled channels is given in Figure 3,
and an AC coupled circuit for 8 channels is shown in
Figure 4. These circuits are suitable for 75
transmission line connections at both the input and the
output and are useful for distribution of wide-band
signals such as video via cables. The 75reverse
terminating resistor at the output gives the correct
matching condition to a terminated video cable. The
amplifier load is then 150.
The wide bandwidth of this device necessitates some
care in the layout of the printed circuit. Partly for this
reason, an Evaluation Circuit board is available and is
described in a later paragraph. A continuous ground
plane is required under the device and its signal
connection paths, to provide the shortest possible
ground return paths for signals and power supply
filtering. A double-sided or multi-layer PCB
construction is required, with plated-through via holes
providing closely spaced low-inductance connections
from some components to the continuous ground
plane (some of these holes are not visible in the figures
for the Evaluation Circuit Board – artworks and NC drill
output can be provided if required).
For the power supply filtering, low inductance surface
mount capacitors are normally required. It has been
found that very good RF decoupling is provided on
each supply using a 1000 pF NPO size 0805 ceramic
surface mount capacitor, closest to the device pin, with
an adjacent 0.1 F X7R capacitor. Other configurations
are possible and it may be found that a single 0.01 F or
0.1 F X7R capacitor, size 0805 or smaller, on each
supply gives good results. However this should be
supported by larger decoupling capacitors elsewhere
on the printed circuit board. Values of 1 to 10 F are
recommended, particularly where the voltage
regulators are located more than a few inches from the
device. These larger capacitors are recommended to
be solid tantalum electrolytic or ceramic types.
Evaluation Circuit
An evaluation circuit is available, constructed on a
double-side printed circuit board. The circuit is suitable
for both the ZXFV301 and ZXFV302 and either device
may be fitted. Figures 5 and 6 show the circuit diagram,
and the layout of components and copper. A parts list
is provided below. This layout serves as a useful
example for many applications, showing the practical
implementation of the advice given above in the
Introduction.
BNC connector sockets allow connection to test
instruments via 50cables. The output circuit includes
a resistor matching circuit to present a load of 150to
the device and simultaneously provide 50output
impedance. The attenuation of this matching circuit is
15.45 dB. As the device has unity voltage gain, the
overall loss when loaded by 75is also 15.45 dB.
