Electrical Connections
The SAW resonator is bidirectional and may be
installed with either orientation. The two terminals
are interchangeable and unnumbered. The callout
NC indicates no internal connection. The NC pads
assist with mechanical positioning and stability.
External grounding of the NC pads is
recommended to help reduce parasitic
capacitance in the circuit.

Land Pattern
The circuit board land pattern
shown below is one possible
design. The optimum land pattern is dependent on the circuit board
assembly process which varies by manufacturer. The distance between
adjacent land edges should be at a maximum to minimize parasitic
capacitance. Trace lengths from terminal lands to other components should
be short and wide to minimize parasitic series inductances.
