Evaluation Board Description
The SKY73134-11 Evaluation Board is used to test the
performance of the SKY73134-11 frequency synthesizer. An
assembly drawing for the Evaluation Board is shown in Figure 8
and the layer detail is provided in Figure 9. A schematic diagram
of the SKY73134-11 Evaluation Board is shown in Figure 10.
Circuit Design Configurations
The following design considerations are general in nature and
must be followed regardless of final use or configuration:
1. Paths to ground should be made as short as possible.
2. The ground pad of the SKY73134-11 has special electrical
