Oscillators 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's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications. Check for any specific environmental operating temperature ranges required by the application to ensure component reliability under operational conditions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable/disable feature for power efficiency. The LVCMOS output is suitable for direct interfacing with standard digital logic families. The small form factor makes it appropriate for space-constrained designs. Consider the manufacturing history of Mercury Electronic as a quartz crystal specialist when evaluating long-term supply stability and frequency accuracy needs.
