Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Check for End-of-Life (EOL) or Not Recommended for New Designs (NRND) notices, as older ECL components may have limited production runs. Ensure compatibility with existing PCB footprints for the 8-SOIC form factor during procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MC100EP140DG when a dedicated PFD is required for 3.3V ECL-based PLL designs. Compare propagation delay specifications and output drive currents against system timing requirements. Consider the MC100EP140 variant if alternative packaging or updated revision data is preferred, ensuring pinout compatibility remains unchanged for direct substitution.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component is part of onsemi's MC100EP series, which focuses on high-performance ECL logic for telecommunications and networking equipment. The EP designation indicates enhanced performance characteristics suitable for demanding signal integrity applications. It serves as a specialized building block for timing control circuits rather than general-purpose logic.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC100EP140D is a documented alias for this component, indicating potential package variations within the same functional family. Verify electrical parameters match exactly before substituting with other PFDs, as output polarity and reset configurations may differ across manufacturers.
