Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and pinout configuration. Ensure the required operating temperature range aligns with the -40°C to +85°C specification. Confirm that the 1.8V supply voltage matches the target circuit design before procurement. Cross-reference the package dimensions with the mechanical drawing to ensure board layout compatibility.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator with enable control is required. The 1.8V supply voltage suits low-power digital designs. The ±50ppm stability meets general timing requirements. Verify that the LVCMOS output levels are compatible with the receiving logic inputs. Consider the 4-SMD package size for space-constrained PCB layouts.
