Oscillators Procurement Notes

Verify that the specific suffix 'Vdd0.9V' matches the required supply voltage for your circuit design, as this variant differs from standard 1.2 V versions. Confirm the '-B' packaging designation aligns with your assembly requirements. Ensure the 50 ppm stability specification meets the system's timing tolerance needs within the specified -40°C to +105°C operating range before finalizing procurement.

Oscillators Selection Notes

Select this component when ultra-low voltage operation at 0.9 V is mandatory for energy efficiency in battery-constrained applications. The 1612 footprint is suitable for high-density PCB layouts where space is limited. Choose this model over higher voltage variants if the system power rail supports 0.9 V and the 50 ppm frequency accuracy is sufficient for the target application's synchronization requirements.

Oscillators Part Context

This part belongs to the FCXO-07F series of high-frequency crystal oscillators from RIVER ELETEC CORPORATION. The series is characterized by its small 1.6x1.2 mm size and robust ceramic construction with a metal lid. These oscillators are designed for applications requiring stable clock signals in compact, low-power environments, utilizing advanced IC technology for immediate output upon power-up.

Oscillators Replacement Considerations

Compatible substitutes include other 25 MHz CMOS oscillators in the 1612 package with similar voltage and stability specs. Verify pin compatibility and electrical characteristics against models like FCXO-07F25.00MVdd1.2V50ppm-40C+105C-B, noting the voltage difference. Cross-reference with industry-standard equivalents ensuring the 0.9 V supply requirement is met.
