Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Cross-reference the part number suffix with the manufacturer's latest documentation to confirm availability and exact specifications.

Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 86.603 MHz applications. The LVCMOS output ensures direct interfacing with standard digital logic families. Consider the 1.8V supply requirement and standby functionality for power-sensitive designs. Verify that the 4-SMD package dimensions fit within the available board space constraints.

Part Context

This model belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers standard frequency outputs with LVCMOS logic levels. The 'PD' suffix likely indicates a specific packaging or tape-and-reel configuration. Mercury Electronics specializes in quartz crystal and oscillator manufacturing, providing frequency control solutions for various electronic industries.

Replacement Considerations

Direct substitutes must match the 86.603 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Check Mercury Electronics datasheets for other variants in the QHTF series with identical electrical parameters. Verify pinout compatibility and thermal characteristics before substitution.
