Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 22.76649 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout. Check for any specific environmental or temperature range requirements not detailed in general descriptions.

Oscillators Selection Notes

Select this component when a 22.76649 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint against available power rails. Evaluate the small 2.0x1.6 mm package size for space-constrained designs. Verify that the standard XO performance meets the application's jitter and stability needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 4-SMD form factor. These components are typically used where reliable quartz-based timing is necessary in consumer or industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 22.76649 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference with other manufacturers offering identical electrical parameters and pinout configurations.
