Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the Enable/Disable pin configuration matches your control logic to ensure proper operational states during standby or active modes.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 23.54 MHz applications. Consider the 1.8V operating voltage and LVCMOS output levels to ensure compatibility with downstream digital components. Evaluate the thermal performance and size constraints of the 4-SMD package within the overall PCB layout.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequency options within the same physical footprint. The series provides standardized XO solutions with consistent electrical characteristics across different frequencies, facilitating inventory simplification for manufacturers producing multiple product variants.

Oscillators Replacement Considerations

Direct replacements must match the 23.54 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical parameters such as phase noise and jitter if critical to the application.
