FMS6364A
Low-Cost Four-Channel Standard Definition (SD)
& High (HD) Definition Video Filter Driver
Features
Description
The FMS6364A Low-Cost Video Filter (LCVF) is
intended to replace passive LC filters and drivers with a
th
low-cost integrated device. Three 7 -order filters
th
provide HD quality and a single 6 -order SD channel
provides compatibility. The FMS6364A may be directly
driven by a DC-coupled DAC output or an AC-coupled
signal. Internal diode clamps and bias circuitry may be
used if AC-coupled inputs are required (see the
Application Information section for details).

The outputs can drive AC- or DC-coupled single (150Ω)
or dual (75Ω) video loads. DC coupling the outputs
removes the need for large output coupling capacitors.
The input DC levels are offset approximately +280mV at
the output (see the Application Information section).

Application Circuits
75Ω
The FMS6364A Low-Cost Video Filter (LCVF) provides
6dB gain from input to output. In addition, the input is
slightly offset to optimize the output driver performance.
The offset is held to the minimum required value to
decrease the standing DC current into the load. Typical
voltage levels are shown in the diagram below:

Figure 15. AC-Coupled Inputs, DC-Coupled Outputs
The FMS6364A provides an internal diode clamp to
support AC-coupled input signals. If the input signal
does not go below ground, the input clamp does not
operate. This allows DAC outputs to directly drive the
FMS6364A without an AC-coupling capacitor. When the
input is AC-coupled, the diode clamp sets the sync tip
(or lowest voltage) just below ground. The worst-case
sync tip compression due to the clamp cannot exceed
7mV. The input level set by the clamp, combined with
the internal DC offset, keeps the output within its
acceptable range.
When the FMS6364A is driven by an unknown external
source or a SCART switch with its own clamping
circuitry, the inputs should be AC coupled as shown in
Figure 16.

The FMS6364A output drive configuration must be
considered when calculating overall power dissipation.
Care must be taken not to exceed the maximum die
junction temperature. The following equations can be

The FMS6364A is specified to operate with output
currents typically less than 50mA, more than sufficient
for a dual (75Ω) video load. Internal amplifiers are
current limited to a maximum of 100mA and should
withstand brief-duration short-circuit conditions. This
capability is not guaranteed.

General layout and supply bypassing play a major role
in
high-frequency
performance
and
thermal
characteristics. Fairchild offers a demonstration board to
guide layout and aid device evaluation. The demo board
is a four-layer board with full power and ground planes.
Following this layout configuration provides optimum
performance and thermal characteristics for the device.
For the best results, follow the steps and recommended
routing rules listed below.
coupling capacitor of choice passes the lowest
frequency content in the video signal and that line time
distortion (video tilt) is kept as low as possible. The
selection of the coupling capacitor is a function of the
subsequent circuit input impedance and the leakage
current of the input being driven. To obtain the highest
quality output video signal, the series termination
resistor must be placed as close to the device output pin
as possible. This greatly reduces the parasitic
capacitance and inductance effect on the output driver.
The distance from device pin to the series termination
resistor should be no greater than 0.5 inches.
Recommended Routing/Layout Rules
Do not run analog and digital signals in parallel.
Do not run traces on top of the ground plane.
Include 0.01μF and 0.1μF ceramic power supply
bypass capacitors.
Place the 0.1μF capacitor within 0.1 inches of the
device power pin.
Use separate analog and digital power planes to
supply power.
Run no traces over ground/power splits.
Avoid routing at 90-degree angles.
Minimize clock and video data trace length
differences.
Place the 0.01μF capacitor within 0.75 inches of the
device power pin.
For multi-layer boards, use a large ground plane to
help dissipate heat.
For two-layer boards, use a ground plane that
extends beyond the device body at least 0.5 inches
on all sides. Include a metal paddle under the
device on the top layer.
Minimize all trace lengths to reduce series
inductance.
Place a 75Ω series resistor within 0.5 inches of the
output pin to isolate the output driver from board
parasitics.
0.5”
Figure 19. Recommended Resistor Placement
Thermal Considerations
Since the interior of systems such as set-top boxes,
TVs, and DVD players are at +70ºC; consideration must
be given to providing an adequate heat sink for the
device package for maximum heat dissipation. When
designing a system board, determine how much power
each device dissipates. Ensure that devices of high
power are not placed in the same location, such as
directly above (top plane) or below (bottom plane), each
other on the PCB.
PCB Thermal Layout Considerations
Output Considerations
The FMS6364A outputs are DC offset from the input by
150mV; therefore VOUT = 2 • VIN DC+150mV. This offset
is required to obtain optimal performance from the
output driver and is held at the minimum value to
decrease the standing DC current into the load. Since
the FMS6364A has a 2x (6dB) gain, the output is
typically connected via a 75Ω-series back-matching
resistor followed by the 75Ω video cable. Because of the
inherent divide by two of this configuration, the blanking
level at the load of the video signal is always less than
1V. When AC coupling the output, ensure that the

FMS6364A • Rev. 3.0.1
Understand the system power requirements and
environmental conditions.
Maximize thermal performance of the PCB.
Make the PCB as thin as possible by reducing FR4
thickness.
Use vias in the power pad to tie adjacent layers
together.
Remember that baseline temperature is a function
of board area, not copper thickness.
Consider modeling techniques a first-order
approximation.
Consider using 70μm of copper for high-power
designs.
