Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this model when a 121.5 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage and standby feature for power efficiency. Evaluate the 3.2x2.5mm package size against available board space. Compare performance metrics such as phase noise and stability if high-precision timing is critical for the application.

Oscillators Part Context

This part belongs to the 18QHTF32 series from Mercury Electronics, which offers various frequencies in a small form factor. The series typically provides standard XO outputs with power-down capabilities. It serves as a timing solution for modern electronics prioritizing miniaturization and low power consumption compared to larger through-hole alternatives.

Oscillators Replacement Considerations

Direct substitutes must match the 121.5 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other Mercury Electronics variants in the same series for potential drop-in replacements.
