RO2073A-17 - 3/25/08
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.
Typical Application Circuits
Equivalent LC Model
Temperature Characteristics
The curve shown on the right
accounts for resonator
contribution only and does not
include LC component
temperature contributions.
Typical
Circuit
Board
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.
Case Design
The case material is black alumina with contrasting symbolization. All pads
are nominally centered with respect to the base and consist of 40 to
70 microinches electroless gold on 60-350 micorinches electroless nickel.
