Oscillators Procurement Notes

Verify the specific ordering suffix and packaging configuration (such as cut tape or reel) against the manufacturer's current datasheet before procurement. Confirm that the selected variant matches the required voltage and tolerance specifications for the target application. Ensure compliance with RoHS directives if environmental regulations apply to the end product. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Oscillators Selection Notes

Select this oscillator when a balance between low cost, small size, and moderate precision (±20ppm) is required. It is suitable for applications where LVCMOS interface compatibility is necessary without additional level shifting. Consider the ±20ppm stability limit against system jitter requirements. Evaluate the 2.5mm x 2.5mm package dimensions against available board space constraints relative to larger MEMS packages.

Oscillators Part Context

This component belongs to the EMRA46 series of MEMS oscillators from Ecliptek, now often associated with Abracon. The series offers various frequencies and tolerances, with the M2H suffix typically indicating specific performance characteristics. These devices are designed to replace traditional quartz crystals in applications demanding better vibration resistance and smaller form factors while maintaining standard digital interface compatibility.

Oscillators Replacement Considerations

Direct replacements include other MEMS oscillators from Ecliptek/Abracon with identical 2.5x2.5mm footprints and LVCMOS outputs, such as the EMK42 series variants, provided frequency and tolerance specs align. Verify pinout compatibility and voltage levels when substituting with parts from different manufacturers like SiTime or Epson.
