Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Ensure the 1.8V supply voltage is stable within the datasheet limits to maintain frequency accuracy. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official manufacturer documentation to avoid assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS signaling is required. The enable/disable feature makes it suitable for battery-operated applications where power conservation is critical. Consider the 4-SMD package size constraints during layout design. Verify that the 82.2091 MHz frequency aligns with the target system's clocking needs.

Part Context

This part belongs to the 18QHTF series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix indicates the presence of an output enable function. Similar parts in the lineup may differ in frequency or voltage but share the same package and logic family characteristics.

Replacement Considerations

Direct replacements must match the 82.2091 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check for equivalent enable/disable functionality. Verify thermal and electrical specifications against original datasheets.
