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.
Typical Test Circuit
The test circuit inductor, LTEST, is tuned to resonate with the static
capacitance, CO, at FC.
