Procurement Notes

Verify the specific frequency tolerance and operating temperature range against your system requirements before ordering. Confirm that the 1.8V supply voltage aligns with your design constraints. Ensure the 4-SMD no-lead package dimensions fit your PCB layout. Check for any specific handling instructions related to surface mount assembly processes.

Selection Notes

Select this model when a 13.530537 MHz reference is required with moderate stability. Consider the LVCMOS interface if it matches your digital logic levels. Evaluate the thermal performance to ensure it remains within the -40°C to 85°C range during operation. Compare the physical footprint against available board space to confirm compatibility with the 4-SMD form factor.

Part Context

This component belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics such as 1.8V operation and LVCMOS outputs. The 'PD' suffix indicates the inclusion of power-down capabilities. These oscillators are designed for reliable performance in consumer and industrial electronic devices requiring accurate clock generation.

Replacement Considerations

Direct substitutes must match the 13.530537 MHz frequency, 1.8V supply, and LVCMOS output type. Verify that alternative components support the same ±50ppm stability and operate within the -40°C to 85°C range. Ensure the replacement uses a compatible 4-SMD no-lead package to maintain mechanical fit. Cross-reference pinouts and electrical specifications to guarantee functional equivalence.
