Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure compatibility with the 1.8V supply rail and confirm that the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer's datasheet for thermal and electrical limits to ensure reliable operation under your intended environmental conditions.

Oscillators Selection Notes

Select this component when a 24.864 MHz clock signal is required with low power consumption. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V operating voltage if your system architecture relies on low-voltage power domains. The small form factor makes it ideal for space-constrained designs where surface-mount technology is preferred over through-hole alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix typically indicates the presence of a power-down or standby feature, distinguishing it from standard continuous-operation variants within the same package family. This specific model provides a fixed frequency solution for timing applications.

Oscillators Replacement Considerations

Direct substitutes include other 24.864 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substitution. Alternative models from the same manufacturer with different frequency ratings may share physical dimensions but will not function as direct replacements without circuit modification.
