Procurement Notes

This component is listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus stock or alternative sourcing channels. Check for RoHS3 compliance status and moisture sensitivity level (MSL 1) prior to procurement planning.

Selection Notes

Select this part for applications requiring a single-input to five-output clock distribution with mixed-mode input compatibility. Ensure the design accommodates the 2.375V to 3.465V supply range. Verify that the 24-VFQFN footprint matches the PCB layout constraints.

Part Context

The 854S015 belongs to the Renesas 854S series of high-performance clock drivers and distributors. This specific variant provides a 2:5 split capability, distinguishing it from other ratios like 1:4 or 1:8 in the same family. It is designed for space-constrained boards requiring high-frequency signal integrity.

Replacement Considerations

The 8T39S06ANBGI is identified as a manufacturer-recommended replacement. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
