Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable functionality is utilized correctly in your schematic to manage power consumption effectively during idle states.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 22.1148 MHz applications. Consider the LVCMOS output compatibility with your downstream logic family. Evaluate the thermal performance and operating temperature range if the device will be used in environments outside standard commercial conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small form factor. The series is characterized by its use of LVCMOS outputs and support for enable/disable controls, catering to modern portable and high-density electronics where size and power efficiency are critical constraints.

Oscillators Replacement Considerations

Direct substitutes must match the 22.1148 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical specifications such as jitter and phase noise if strict timing integrity is required.
