TYPICAL APPLICATION CIRCUIT
The figure above shows the recommended application
circuit for the GS1515. The external VCO is the GO1515
and is specifically designed to be used with the GS1515.
Figures 24 through 28 show an example PC board layout of
the GS1515 IC and the GO1515 VCO. This application
board layout does not reflect every detail of the typical
application circuit but is used as a general guide to the
location of the critical parts. For further circuit and layout
details, refer to the EB1504/15 Evaluation Board Application
Note.
