The following figure shows the CLK104 RF clock add-on card and its components.
Each numbered component referenced in the figure is described in the table and sections
that follow.
CAUTION:
The CLK104 add-on card must be secured to the evaluation board with three screws
before operation. The mounting holes are shown in the figure.
Important: The figure is
for reference only and might not reflect the current revision of the board.
