1.
The inside radius of all 24 half holes at the perimeter of
the board are plated to provide a surface for the
attachment of the PLL Module to the PCB. 16 pads are
for grounding, 8 pads are for signal interface.
2.
The surface of the shield is tin-plated and may be
soldered to. The shield's base metal is cold-rolled steel.
3.
The ground plane on the bottom side is ground and
attaches to a ground track on the top side of the board
as well as to the shield.
4.
Unless otherwise noted all dimensions are in inches.
