Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 17.7345 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check for any specific handling instructions regarding electrostatic discharge sensitivity during assembly.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V logic systems. Consider the ±50ppm stability requirement against system timing tolerances. Evaluate the thermal performance within the -40°C to 85°C range for environmental suitability. Compare physical dimensions against available board space constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form-factor oscillators. The series typically includes various frequencies and voltage options. The 'OE' suffix often denotes specific ordering or packaging configurations. Mercury Electronics specializes in quartz-based frequency control products including crystals and oscillators.

Oscillators Replacement Considerations

Direct substitutes must match the 17.7345 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics before substitution. Consult manufacturer cross-reference lists for approved alternatives.
