Feature Summary

• Surface-acoustic-wave technology for fundamental-mode quartz frequency control
• Single-port configuration designed as a frequency control element in transmitters

Applications

• Transmitter frequency control
• Surface-mount electronic assemblies
• RF signal generation circuits

Procurement Notes

Verify the specific suffix against official RFMi documentation to confirm exact electrical tolerances and thermal ranges, as variations exist within the series. Ensure compatibility with surface-mount reflow processes and check for RoHS compliance status prior to integration into final designs.

Selection Notes

Select this component when a precise 868.95 MHz reference is required for transmitter applications. The 32 ppb stability suits systems needing tight frequency accuracy. Confirm that the 3x3 mm footprint and 1.38 mm height fit the PCB layout constraints and thermal management requirements of the target environment.

Part Context

This part belongs to the RFMi SAW resonator family, which includes single-port and dual-port types. These devices are engineered specifically to serve as stable frequency control elements within radio frequency transmitter architectures, offering reliable performance in compact surface-mount packages.

Replacement Considerations

Consult official substitution lists for compatible alternatives. Generic cross-references may not match the specific 32 ppb stability or package dimensions.
