Application Specific Clock/Timing Procurement Notes

This component is officially discontinued by the manufacturer. Availability is restricted to existing stock or surplus channels. Verify RoHS compliance status carefully, as specific suffixes may indicate non-compliant variants in legacy inventory. Confirm package integrity and lead condition before integration into new designs.

Application Specific Clock/Timing Selection Notes

Engineers should evaluate alternative active components due to the discontinuation status. Ensure replacement parts match the 48-TSSOP footprint and 2.3V–2.7V operating voltage. Verify that substitute devices maintain the required 1:10 fan-out capability and SSTL-2 output levels for compatibility with target memory controllers.

Application Specific Clock/Timing Part Context

The 95V857AGLFT belongs to the 95V857 family of clock buffers designed for high-performance memory systems. It serves as a critical interface between system clocks and DDR memory modules, ensuring precise timing alignment through its zero-delay feedback loop mechanism.

Application Specific Clock/Timing Replacement Considerations

Publicly confirmed direct substitutes are not available in the provided documentation. Engineers must identify equivalent active parts from current Renesas portfolios or other manufacturers that support DDR clock buffering with similar pinouts and electrical characteristics.
