Procurement Notes

The 889874AKLF is classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement components. Procurement should prioritize verified substitute part numbers such as the NB6L611MNG or SY89876LMG to ensure long-term supply chain stability.

Selection Notes

Designers requiring this component must account for its discontinued status. Selection should focus on compatible replacements that match the 2.5 GHz frequency, 1:2 ratio, and LVPECL output specifications. Verify that alternative packages and pinouts are compatible with existing PCB layouts before finalizing the design change.

Part Context

This component belongs to the ICS889874 family of high-performance clock buffers. It is designed for applications requiring precise clock distribution with low jitter. The device integrates multiple clocking functions into a single package to reduce board space and complexity in high-speed data transmission systems.

Replacement Considerations

Publicly confirmed substitutes include the NB6L611MNG from onsemi and the SY89876LMG from Microchip Technology. These alternatives offer similar performance characteristics and should be evaluated for pin compatibility and electrical parameter alignment.
