Electrical Connections
The SAW resonator is bidirectional and may be in-
stalled 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 recommend-
ed to help reduce parasitic capacitance in the cir-
cuit.
Typical Test Circuit
The test circuit inductor, LTEST, is tuned to resonate with the static capaci-
tance, CO, at FC.

Temperature Characteristics
The curve shown on the right
accounts for resonator contri-
bution only and does not in-
clude LC component tempera-
ture contributions
.
Typical Circuit Board
Land Pattern
The circuit board land pattern shown below is one possible design. The op-
timum 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 mini-
mize parasitic series inductances.
