Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct frequency and package variant. Confirm that the OE suffix aligns with required lead-free specifications. Cross-reference the DigiKey part number 5672-18QHTF21-20.037-OE-ND with official datasheets to validate electrical parameters before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 20.037 MHz clock source is required with low voltage operation. Ensure the design accommodates the 1.8V supply requirement and LVCMOS output swing. Verify that the 4-SMD footprint matches the PCB layout constraints and that thermal management requirements are met for the selected operating environment.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics 18QHTF series, which provides standard frequency generation solutions. The series typically offers various frequency options within a consistent form factor. Mercury Electronics has established itself as a quartz crystal manufacturer since 1973, providing frequency control products for industrial applications.

Oscillators Replacement Considerations

Direct substitutes must match the 20.037 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and enable/disable functionality. Check if alternative manufacturers offer equivalent performance metrics for the same application requirements.
