Procurement Notes

Verify the specific suffix against official manufacturer documentation to ensure accurate frequency and package specifications. Confirm that the ordering code matches the required electrical parameters and thermal ratings. Cross-reference the part number with authorized distributors to validate authenticity and availability. Ensure the component meets the intended environmental operating conditions before integration into the final design.

Selection Notes

Select this component when a precise 114.87 MHz clock source is required for LVCMOS-compatible circuits. Consider the 1.8V supply requirement and the small form factor for space-constrained designs. Evaluate the ±50ppm stability against system timing requirements. Verify the -40°C to 85°C temperature range aligns with the operational environment of the target application.
