FMXR1002

Overview

The FMXR1002 is a standard clock oscillator manufactured by Fairview Microwave, designed as a free-running reference source operating at a frequency of 100 MHz. It features a surface-mount (SMT) package with dimensions of 0.9 inches and utilizes an internal reference for stability. The device exhibits a phase noise performance of -155 dBc/Hz and maintains a frequency stability of 5 PPM. It supports a supply voltage range of 3.0 V to 3.6 V and draws a maximum current of 40 mA. The operational temperature range spans from -30°C to +70°C, with termination provided via SMD/SMT interfaces.

Feature Summary

• Provides a stable 100 MHz free-running reference signal using an internal oscillator reference.
• Utilizes a compact 0.9-inch surface-mount package for efficient PCB integration.
• Delivers low phase noise performance of -155 dBc/Hz for precise timing applications.
• Operates within a wide industrial temperature range from -30°C to +70°C.

Applications

• High-precision timing reference sources in electronic systems
• Clock distribution networks requiring low phase noise
• Test and measurement equipment calibration references
• Communication systems requiring stable 100 MHz signals

Procurement Notes

Verify the specific ordering suffixes and package variants available through authorized distributors such as Mouser Electronics. Confirm that the selected unit matches the required SMT footprint and electrical specifications for your design. Check current availability status, as supply may be limited or subject to release schedules. Ensure compliance with RoHS and other relevant environmental standards before final procurement decisions.

Selection Notes

Select this component when a 100 MHz free-running clock with high spectral purity is required. The internal reference simplifies design by eliminating external crystal dependencies. Consider the 0.9-inch SMT package size for board space constraints. Verify that the 3.0 V to 3.6 V supply range aligns with your system power architecture and that the -155 dBc/Hz phase noise meets your application's jitter requirements.

Part Context

The FMXR1002 belongs to Fairview Microwave's standard clock oscillator product line, which focuses on providing reliable reference solutions for RF and microwave applications. This series emphasizes compact form factors and robust performance characteristics suitable for demanding environments. As part of the broader portfolio, it complements other passive and active components offered by the manufacturer for complete system integration needs.

Replacement Considerations

Consult official Fairview Microwave documentation for direct cross-reference alternatives. Verify pinout compatibility and electrical parameter equivalence if substituting with similar oscillators from other manufacturers. Ensure that any replacement maintains the required 100 MHz frequency and phase noise specifications.
