853S310CVILFT

Overview

The Renesas Electronics Corporation 853S310CVILFT is a low skew, high-performance 1-to-8 differential-to-3.3V LVPECL/ECL fanout buffer. It features selectable differential input pairs (PCLKx, nPCLKx) that accept LVPECL, LVDS, CML, and SSTL signal levels. The device provides eight differential 3.3V LVPECL/ECL outputs and operates within a supply voltage range of 2.375V to 3.8V. It supports maximum frequencies up to 2.5 GHz and functions across an operating temperature range of -40°C to 85°C. The component is housed in a surface-mount package.

Feature Summary

• Provides one-to-eight clock distribution with low skew performance
• Accepts multiple differential input signal standards including LVPECL, LVDS, CML, and SSTL
• Generates eight differential 3.3V LVPECL/ECL output signals

Applications

• Networking equipment clock distribution
• Communications infrastructure timing
• Computing system clock buffering

Procurement Notes

This component is classified as obsolete and is no longer manufactured by Renesas Electronics Corporation. Procurement should focus on identifying verified replacement part numbers or alternative components from other manufacturers that meet the same electrical specifications and pin compatibility requirements. Availability through standard distribution channels is restricted.

Selection Notes

Engineers requiring this specific functionality must evaluate alternative solutions due to the discontinued status of the 853S310CVILFT. Selection criteria should prioritize devices offering identical 1:8 fanout ratios, compatible 3.3V LVPECL/ECL outputs, and support for the required input signal formats such as LVDS and CML to ensure seamless integration into existing designs.

Part Context

The 853S310I belongs to Renesas' family of high-performance clock buffers designed for demanding networking and communications applications. This series emphasizes low skew characteristics to maintain signal integrity across multiple output branches. The CVILFT suffix indicates specific packaging and compliance attributes associated with the manufacturer's product line.

Replacement Considerations

Public confirmed substitute part numbers include MC10EP89DG from onsemi. Designers should verify functional equivalence regarding input/output voltage levels and signal compatibility before implementing any cross-manufacturer substitution.
