Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable/disable feature for power efficiency. The LVCMOS output is appropriate for direct interfacing with standard digital logic families. Consider the small form factor of the 4-SMD package for space-constrained designs where surface mounting is preferred over through-hole technologies.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control solutions. The series typically includes various oscillators such as TCXOs and VCTCXOs. This specific model represents a standard XO variant designed for general-purpose timing applications within consumer and industrial electronics sectors.

Oscillators Replacement Considerations

Direct substitutes must match the 14.475 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify electrical parameters including phase noise and jitter specifications to ensure functional equivalence in high-speed digital environments.
