Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix D06802 against the target design requirements. Confirm that the ordering part number matches the required frequency plan and operational parameters before procurement. Ensure compatibility with the ClockBuilder Pro software settings used during initial programming.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed, preconfigured clock solution is preferred over field-programmable devices. The Si5344A variant supports both integer and fractional synthesis modes up to 1028 MHz. Verify that the application requires the specific frequency plan encoded in the D06802 suffix rather than a generic blank prototyping device.
