5. Application Information
5.1 PCB Layout
Special attention must be paid to component layout when designing serial digital
interfaces for HDTV.
An FR-4 dielectric can be used, however, controlled impedance transmission lines
are required for PCB traces longer than approximately 1cm. Note the following
PCB artwork features used to optimize performance:
The PCB trace width for HD rate signals is closely matched to SMT
component width to minimize reflections due to changes in trace impedance.
The PCB groundplane is removed under the GS1578A output components to
minimize parasitic capacitance.
The PCB ground plane is removed under the GS1578A R
SET
pin and resistor
to minimize parasitic capacitance.
Input and output BNC connectors are surface mounted in-line to eliminate a
transmission line stub caused by a BNC mounting via high speed traces which
are curved to minimize impedance variations due to change of PCB trace
width.
