Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The integrated enable/disable feature allows for power management strategies in battery-operated devices. Consider the physical dimensions of the 4-SMD package to ensure compatibility with space-constrained printed circuit board designs.
Part Context
This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These components are designed to replace through-hole crystals or larger oscillator packages in modern miniaturized electronic assemblies requiring precise timing signals.
Replacement Considerations
Direct substitutes include other 10.15 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substitution. Cross-reference with similar Mercury Electronics models like the 18QHTF21-10.180-OE if frequency adjustments are permissible.
