Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The 843011AGLF is listed as an obsolete or end-of-life product by major distributors. Verification of current stock availability through authorized channels is required before procurement planning. Alternative sourcing strategies should be considered due to limited supply chain support for discontinued components.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Designers should verify that the required output frequency falls within the operational range of the 843011 series. Ensure compatibility with the 8-TSSOP footprint and confirm that the LVPECL output swing matches the receiving device's input requirements. Thermal management considerations for the TSSOP package should be evaluated based on system power dissipation limits.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Renesas FemtoClock family, which specializes in low-jitter clock generation solutions. The 843011 series typically offers fixed multiplication ratios or specific frequency synthesis options tailored for standard communication protocols. It serves as a replacement for legacy IDT clock synthesizers in established designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements may include other members of the 843011 series with different suffixes indicating package or temperature variations. Cross-reference with IDT/Integrated Device Technology equivalents such as the 89N3xxx series may be necessary for functional parity in existing circuits.
