Oscillators Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct operational parameters. Confirm that the OE suffix aligns with the required enable/disable functionality and voltage specifications before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Oscillators Selection Notes

Select this component when a 38.84 MHz clock signal is required with low voltage operation. Ensure the design supports LVCMOS logic levels and provides the necessary enable control signal. Verify that the 4-SMD footprint matches the PCB layout constraints and thermal requirements of the target application.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, a manufacturer established in 1973 specializing in quartz crystals and oscillators. The series is designed for computing and data communication markets, offering reliable frequency control solutions with various output types and supply voltages.

Oscillators Replacement Considerations

The 18QHTF21-38.840-PD is a related variant within the same series but typically lacks the enable/disable feature found in the OE suffix version. Verify functional differences before substitution.
