Oscillators Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Production has ceased, and the part will be discontinued. Procurement should focus on verifying final availability through authorized channels or identifying suitable replacement components that meet identical electrical specifications and form factor requirements before committing to orders.

Oscillators Selection Notes

Select this oscillator when a 66.666MHz LVCMOS signal is required in a compact 2.5mm x 3.2mm footprint. Ensure the application environment remains within the -40°C to +85°C operational range. Verify that the ±50ppm frequency stability meets system timing accuracy needs. Confirm compatibility with 1.8Vdc logic levels and check if power-down control is utilized in the design.

Oscillators Part Context

The EMRA31K1J-66.666M TR belongs to the EMRA31 series of programmable MEMS oscillators manufactured by Ecliptek. This series provides standard clock solutions with small form factors. The specific model denotes a 66.666MHz frequency variant with LVCMOS output. The 'TR' suffix indicates tape and reel packaging for automated assembly processes.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the End-of-Life status. Users must evaluate alternative MEMS oscillators from other manufacturers that match the 66.666MHz frequency, LVCMOS output, 2.5mm x 3.2mm package, and ±50ppm stability specifications.
