854110AYILFT

Overview

The 854110AYILFT is a clock buffer manufactured by Renesas Electronics, formerly part of the Integrated Circuit Specialties (ICS) product line. It functions as a differential HCSL fanout buffer designed to translate various differential input signal levels into differential HCSL outputs without requiring external bias networks. The device supports maximum output frequencies up to 250MHz and operates on a full 3.3V supply voltage. Key electrical parameters include a maximum output skew of 165ps, part-to-part skew of 250ps, and output drift of 140ps. The high-impedance VOH reaches a maximum of 850mV. It is characterized for ambient operating temperatures ranging from 0°C to 70°C.

Feature Summary

• Provides ten differential HCSL outputs for clock distribution
• Translates LVPECL, LVHSTL, LVDS, or HCSL inputs to HCSL levels without external bias
• Supports maximum output frequency of 250MHz
• Operates at a full 3.3V supply voltage

Applications

• PCI Express interface systems
• Fully Buffered DIMM (FBDIMM) applications
• High-speed digital system clock distribution

Procurement Notes

Verify component status prior to procurement as this specific part number may be obsolete or discontinued within the manufacturer's portfolio. Confirm availability through authorized distributors and check for moisture sensitivity level (MSL) requirements during storage and handling. Ensure the package type matches the design constraints, typically TQFP for this series.

Selection Notes

Select this component when a single differential input needs to drive ten differential HCSL loads with low skew characteristics. Ensure the input signal format (LVPECL, LVDS, etc.) is compatible with the translation capabilities. Verify that the 3.3V supply voltage aligns with the system power architecture and that the 0°C to 70°C operating temperature range meets environmental specifications.

Part Context

This component belongs to the ICS 854110 family of differential HCSL fanout buffers. It shares functional similarities with other models in the series, such as the 851010 (1-to-10) and 851021 (1-to-21), which offer different output counts but similar signal translation features. These devices are commonly used in legacy high-speed data communication and computing infrastructure designs.

Replacement Considerations

Direct replacement options should be sought among other 1-to-10 differential HCSL fanout buffers from Renesas or former ICS lines. Verify pin compatibility and electrical parameter equivalence, specifically output skew and supply voltage, before substituting.
