4. Application Information  
4.1 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 GS1528 output components to  
minimize parasitic capacitance  
The PCB ground plane is removed under the GS1528 RSET pin and resistor to  
minimize parasitic capacitance  
Input and output BNC connectors are surface-mounted in-line to eliminate  
transmission line stubs caused by a BNC mounting via high-speed traces, which are  
curved to minimize impedance variations due to change of PCB trace width
