ADA4410-6
Rev. B | Page 15 of 16
PRINTED CIRCUIT BOARD LAYOUT
When the ADA4410-6 receives its inputs from a device with
current outputs, the required load resistor value for the output
current is often different from the characteristic impedance of
the signal traces. In this case, if the interconnections are sufficiently
short (<< 0.1 wavelength), the trace does not have to be terminated
in its characteristic impedance. Figure 27 shows an example in
which the ADA4410-6 input originates from DACs that require
300 Ω load resistors. Traces of 75 Ω can be used in this instance,
provided their lengths are an inch or two at the most. This is
easily achieved because the ADA4410-6 and the device feeding
it are usually adjacent to each other, and connections can be
made that are less than one inch in length.
As with all high speed applications, attention to printed circuit
board layout is of paramount importance. Standard high speed
layout practices should be adhered to when designing with the
ADA4410-6. A solid ground plane is recommended, and
surface-mount ceramic power supply decoupling capacitors
should be placed as close as possible to the supply pins. All of
the ADA4410-6 GND pins should be connected to the ground
plane with traces that are as short as possible. Controlled
impedance traces of the shortest length possible should be used
to connect to the signal I/O pins and should not pass over any
voids in the ground plane. A 75 Ω impedance level is typically
used in video applications. All signal outputs of the ADA4410-6
should include series termination resistors when driving
transmission lines.
VIDEO ENCODER RECONSTRUCTION FILTER
The ADA4410-6 is easily applied as a reconstruction filter at the
DAC outputs of a video encoder. Figure 27 illustrates how to use
the ADA4410-6 in this type of application with an ADV7314 video
encoder in a single-supply application with ac-coupled outputs.
