Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 4.42368 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the LVCMOS output type is compatible with the receiving logic inputs. Check that the operating temperature range meets the environmental requirements of the final application.

Oscillators Selection Notes

Select this component when a stable 4.42368 MHz reference is needed for 1.8V logic families. Consider the ±50ppm stability requirement against system timing tolerances. Evaluate the physical dimensions of the 4-SMD package against available PCB space. Verify that the enable pin functionality is utilized or left unconnected as per design needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations in manufacturer catalogs. These components are designed for high-volume manufacturing integration.

Oscillators Replacement Considerations

Direct substitutes must match the 4.42368 MHz frequency, 1.8V supply, and LVCMOS output. Compatible packages include 4-SMD No Lead types. Verify pinout compatibility if replacing with different manufacturers. Ensure equivalent frequency stability and temperature range specifications.
