Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm exact electrical parameters and pinout configuration. Ensure compatibility with 1.8V supply rails and LVCMOS logic thresholds before integration. Cross-reference the 4-SMD footprint dimensions with PCB layout requirements to guarantee mechanical fit and soldering reliability during assembly processes.

Oscillators Selection Notes

Select this component when a 20.7 MHz reference clock is required with low voltage operation. Consider the enable/disable feature for power management strategies in battery-operated devices. Evaluate thermal performance within the -40°C to 85°C range if operating in industrial environments. Confirm that LVCMOS output swing meets the input requirements of the downstream digital circuitry.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package. These components are designed to replace through-hole crystals with integrated oscillator solutions, simplifying board design and improving timing accuracy compared to discrete crystal setups.

Oscillators Replacement Considerations

Direct substitutes include other 20.7 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin-to-pin compatibility and output voltage levels before substitution. Alternative parts must support the same enable/disable control mechanism if power management is critical to the application design.
