Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially discontinued by the manufacturer. End-of-Life (EOL) notification was published on April 26, 2018. Current availability is limited to existing stock from distributors; no new production units are available. Verification of authenticity and storage history is critical when sourcing from secondary markets due to the part's obsolete status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Designers requiring this specific frequency and package configuration must evaluate alternative clock synthesizers from current Renesas portfolios or other manufacturers. Considerations should include pin compatibility, supply voltage requirements, and jitter performance specifications to ensure seamless integration into existing designs without re-verification of all system-level timing constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MK2703 series belongs to Renesas' legacy portfolio of clock generators. The 'SLFTR' suffix indicates the tape-and-reel packaging format within the SOIC-8 footprint. This part is distinct from other MK series variants which may offer different frequencies or output configurations.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

No direct public substitute part numbers are confirmed for this discontinued model. Engineers should consult Renesas application notes for recommended modern replacements or perform a full redesign using contemporary low-jitter clock synthesizers.
