Programmable Oscillators Procurement Notes

Verify the specific programmed frequency against the manufacturer's datasheet or configuration tool before procurement, as this is a programmable device. Confirm that the CML output interface matches the receiving circuit's input requirements. Ensure the 3.3 V supply voltage aligns with the system design. Check for RoHS compliance status if required by project specifications.

Programmable Oscillators Selection Notes

Select this model when a programmable clock source with CML outputs is required. Compare it against fixed-frequency oscillators if frequency agility is not needed. Consider the 25 PPM stability requirement against system jitter budgets. Verify the SMD7050-6P footprint compatibility with the PCB layout. Evaluate power consumption against thermal constraints in dense assemblies.
