Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required voltage and output specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Request the official datasheet directly from Geyer Electronic America, Inc. or authorized distributors to validate electrical characteristics and thermal performance data before finalizing procurement decisions.

Selection Notes

Select this component when a stable 8 MHz reference is required for low-voltage digital circuits. Ensure the design accommodates the 1.8V to 3.3V supply range and utilizes the tri-state feature if bus sharing is necessary. Verify that the ceramic construction meets the environmental requirements for the intended application temperature range.

Part Context

This oscillator belongs to Geyer Electronic's line of ceramic SMD oscillators, which are engineered for cost-effective frequency control solutions. These components typically replace discrete crystal and load capacitor networks, simplifying board layout while maintaining stability. The 12.95219 model specifically targets applications requiring standard HCMOS outputs in space-constrained designs.

Replacement Considerations

Cross-reference part numbers such as those from Silicon Labs (e.g., SI1084 series) for potential functional equivalents. Ensure that any substitute matches the 8 MHz frequency, HCMOS output type, and 4-SMD package outline to maintain mechanical and electrical compatibility without redesigning the host circuit.
