Oscillators Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm electrical characteristics and package type. Ensure the ordering code matches the required frequency and voltage specifications. Cross-reference the part number with official Mercury Electronics datasheets to validate availability and compliance status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage LVCMOS oscillator is required for space-constrained designs. The 1.8V supply and enable feature make it suitable for battery-powered or power-sensitive applications. Confirm that the 40.0 MHz frequency aligns with the target system's clock requirements and that the 2.0x1.6 mm footprint fits the PCB layout constraints.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a consistent small form factor. The -OE suffix typically denotes specific packaging or configuration details defined by the manufacturer, distinguishing it from other variants in the same product line.

Oscillators Replacement Considerations

Direct substitutes include other 40.0 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as load capacitance and drive strength. Alternative models from different manufacturers must match the physical dimensions and functional specifications to ensure seamless integration.
