Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a 93.75 MHz reference is required with low voltage operation. Consider the LVCMOS output swing for direct interfacing with digital logic. Evaluate the thermal performance within the SMD package for your operating environment. Compare power consumption in standby mode against other oscillator options to optimize system efficiency.
Part Context
This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down feature. This family targets applications needing reliable timing in space-constrained designs.
Replacement Considerations
Direct substitutes include other 93.75 MHz LVCMOS oscillators from Mercury Electronics such as the 25QHTF57-93.750-PD, noting the package difference. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers.
