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 footprint matches your PCB layout constraints. Cross-reference the part number suffix to confirm the exact variant specifications provided by the manufacturer.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the small form factor of the 4-SMD package for space-constrained designs.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The series offers various standard frequencies with consistent packaging and electrical characteristics, facilitating standardized design processes across different product lines within the manufacturer's portfolio.

Oscillators Replacement Considerations

Direct substitutes must match the 27.12015 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify compatibility with existing PCB footprints and thermal requirements. Consult manufacturer cross-reference lists for equivalent parts with identical pinouts and electrical specs.
