Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the 1.8V supply voltage aligns with your power management architecture. Confirm that the enable/disable pin configuration matches your control logic to ensure proper operation during standby or active states.

Selection Notes

Select this component when a 69.248 MHz reference is required with low-voltage 1.8V operation. Consider the LVCMOS output level for direct interfacing with compatible digital inputs. Evaluate the 4-SMD footprint constraints within the PCB layout to ensure adequate clearance and thermal performance for the no-lead package type.

Part Context

This model belongs to the 18QHTF series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies with consistent 1.8V LVCMOS specifications. The 'OE' suffix indicates specific ordering or packaging variations defined by the manufacturer for this particular frequency variant.

Replacement Considerations

Direct substitutes include other 69.248 MHz XO devices with matching 1.8V LVCMOS outputs and 4-SMD packages. Verify electrical parameters such as phase noise and jitter specifications to ensure functional equivalence in timing-critical applications.
