8S58021AKILFT

Application Specific Clock/Timing Overview

The Renesas 8S58021AKILFT is a differential-to-LVPECL/ECL fanout buffer operating at frequencies up to 2.5 GHz. It features one input and four outputs with non-inverting polarity, housed in a 16-lead VFQFPN package. The device operates on a supply voltage ranging from 2.375 V to 3.465 V, drawing approximately 80 mA of quiescent current. It supports an industrial temperature range from -40°C to +85°C and includes moisture sensitivity classification for surface-mount assembly.

Application Specific Clock/Timing Feature Summary

Application Specific Clock/Timing Procurement Notes

Verify the suffix 'AKILFT' confirms RoHS compliance and lead-free termination. Confirm the package marking matches the 16-VFQFPN specification. Check the datasheet revision date to ensure compatibility with current design requirements. Validate that the 2.375 V to 3.465 V supply range aligns with the target system power rails. Ensure thermal management strategies account for the 80 mA operating current.

Application Specific Clock/Timing Selection Notes

Select this component when a differential signal must be converted to LVPECL or ECL standards for high-speed distribution. The 1:4 fanout ratio suits applications requiring multiple synchronized loads from a single source. Verify that the 2.5 GHz maximum frequency meets the specific data rate needs. Consider the VFQFPN package size for PCB layout constraints compared to larger QFN or BGA options.
