Procurement Notes
Verify the exact frequency specification of 74.2125 MHz against design requirements. Confirm the 1.8V supply voltage compatibility with the target circuit. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check for the presence of the enable/disable pin functionality if power management is required.
Selection Notes
Select this component when a fixed frequency of 74.2125 MHz is required with LVCMOS outputs. Consider the 1.8V operating voltage for low-power designs. The enable/disable feature allows for dynamic power control. Verify thermal performance within the specified operating temperature range for the application environment.
Part Context
This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies with consistent LVCMOS output and enable/disable capabilities. The -OE suffix typically denotes specific ordering or packaging variations within the manufacturer's catalog structure.
Replacement Considerations
Direct substitutes include other 74.2125 MHz LVCMOS oscillators with identical 4-SMD no-lead footprints and 1.8V operation. Verify pinout compatibility and enable/disable functionality before substitution. Cross-reference with Mercury Electronics' official replacement lists for guaranteed compatibility.
