Oscillators Procurement Notes

Verify the exact part number against official Mercury Electronics documentation to ensure compatibility with specific design requirements. Confirm that the 3.3V supply voltage and LVCMOS output levels match the target circuit specifications. Check the 4-SMD package dimensions for PCB layout alignment. Ensure the operating temperature range meets the environmental conditions of the intended application before procurement.

Oscillators Selection Notes

Select this component when a 3.183671 MHz clock source is required with LVCMOS compatibility. Consider the 3.3V supply constraint and the availability of standby functionality for power-sensitive designs. Evaluate the 4-SMD footprint against available board space. Compare performance against other Mercury QHTF series variants if different frequencies or voltages are needed.

Oscillators Part Context

This model belongs to the QHTF series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages within a consistent 4-SMD form factor. The 'PD' suffix likely indicates a specific packaging or testing configuration provided by distributors. Mercury Electronics specializes in quartz crystal components with extensive industry history.

Oscillators Replacement Considerations

Direct substitutes may include other 3.183671 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson or SiTime, provided electrical parameters match. Verify pinout compatibility and supply voltage tolerance. Cross-reference with Mercury's own product line for alternative packages or frequencies if minor adjustments are permissible.
