APPLICATION INFORMATION
PCB LAYOUT
Special attention must be paid to component layout when
designing serial digital interfaces for HDTV. Figures 23
through 27 show the artwork for a four layer printed circuit
evaluation board for the GS1504. The schematic is shown in
Figure 22. An FR-4 dielectric can be used, however,
controlled impedance transmission lines are required for
PCB traces longer than approximately 1cm. Note the
following

to
optimize
PCB trace width for HD rate signals is closely matched
to SMT component width to minimize reflections due to
change in trace impedance.
The PCB ground plane is removed under the GS1504
input components to minimize parasitic capacitance.
The PCB ground plane is removed under the GS1504
output components to minimize parasitic capacitance.
High speed traces are curved to minimize impedance
changes.
A picture of the GS1504 PCB assembly is shown in Figure
28.
