Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape and reel packaging requirements. Ensure the selected variant matches the required supply voltage and frequency tolerance specifications for the target application environment. Cross-reference the pin configuration with the official datasheet to guarantee correct footprint alignment during PCB design and assembly planning.

Oscillators Selection Notes

Select this component when a 25 MHz clock source with LVCMOS output is required for surface-mount designs. Consider the ±25 ppm stability specification for applications demanding moderate precision. Evaluate the -40°C to +85°C operating range against environmental conditions. Confirm that the 4-pin SMD package dimensions fit within the available board space constraints.

Oscillators Part Context

This part belongs to the EC37 series of standard clock oscillators from Ecliptek. The series offers various frequency options and stability grades within a consistent 3.2mm x 5.0mm form factor. Similar models include variants with different frequencies such as 33.333 MHz or 25.000 MHz with differing stability ratings like ±50 ppm.

Oscillators Replacement Considerations

Direct substitutes may include other 25 MHz LVCMOS oscillators in 4-SMD packages with matching electrical parameters. Verify pinout compatibility and voltage levels before substitution. Models like EC3745ETTS-33.333M TR share the same package but differ in frequency.
