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 no lead footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD no lead form factor for space-constrained layouts requiring reliable surface-mount technology without through-hole constraints.
Part Context
This part belongs to the Mercury Electronic 18QHTF21 series of standard XO oscillators. The series typically offers various frequencies with consistent electrical characteristics and packaging. Mercury Electronic specializes in quartz crystals and timing solutions, providing these components for industrial and consumer electronics applications requiring precise frequency control.
Replacement Considerations
Direct substitutes must match the 10.0408 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and thermal performance. Cross-reference with other manufacturers offering identical envelope dimensions and electrical specs to ensure seamless integration without redesign.
