Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by MaxLinear. Verification of current availability should focus on secondary market sources or existing stock rather than direct manufacturer distribution. Confirm end-of-life status through official product discontinuance notices before procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part only if LVPECL output compatibility and a 156.25 MHz maximum frequency are required. Ensure the design accommodates the 2.375 V to 3.465 V supply range and the specific thermal characteristics of the 10-VQFN package. Verify that the obsolete status aligns with long-term production requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The XR81111-CA04-F is part of the XR81111 family of universal clock synthesizers. These devices are engineered to provide flexible frequency generation capabilities. The specific CA04 suffix denotes the LVPECL output variant within this series, distinguishing it from other output types available in the broader family.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

No public confirmed substitute part numbers are documented for this obsolete component. Designers must evaluate alternative clock synthesizers from MaxLinear or other manufacturers that meet the LVPECL and frequency specifications.
