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 4-SMD no-lead footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated standby feature makes it suitable for battery-powered or energy-efficient designs. Consider the small form factor of the 4-SMD package for space-constrained boards. Verify that the 48.012 MHz frequency meets the exact timing needs of the target application.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides stable clock signals for various electronic circuits. The manufacturer specializes in quartz crystals and oscillators, offering a range of frequencies and packages. The 18QHTF21 series typically targets applications needing reliable timing in a minimal footprint.

Oscillators Replacement Considerations

Direct substitutes must match the 48.012 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers' 4-pin SMD oscillators operating at the same voltage and frequency.
