Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm the 4-SMD package dimensions fit the PCB footprint requirements. Check for any RoHS compliance documentation if required by the project specifications.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for standard digital logic interfaces. Consider the standby feature for power-sensitive designs. Verify that the 13.526 MHz frequency meets the system clock requirements. Ensure the surface mount package type matches the assembly capabilities.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V LVCMOS outputs. Similar models include variants like 18QHTF21-8.000-PD and 18QHTF21-51.200-PD, which share the same package and electrical characteristics but differ in output frequency.

Oscillators Replacement Considerations

Direct substitutes must match the 13.526 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference with other manufacturers offering identical pinout and electrical specs. Verify thermal performance and stability ratings match the original application requirements.
