851010AYLFT

Overview

The 851010AYLFT is a 1-to-10 Differential HCSL Fanout Buffer manufactured by Renesas Electronics. It translates differential input signals (LVPECL, LVHSTL, LVDS, HCSL) to HCSL levels without external bias networks. Key electrical parameters include a maximum output frequency of 250MHz, maximum output skew of 165ps, part-to-part skew of 250ps, and output drift of 140ps. The device operates on a full 3.3V supply voltage with a maximum VOH of 850mV. It is characterized for an ambient operating temperature range of 0°C to 70°C.

Feature Summary

• Ten differential HCSL outputs
• Translates LVPECL, LVHSTL, LVDS, or HCSL inputs to HCSL levels
• Maximum output frequency of 250MHz
• Low skew specifications: 165ps output skew, 250ps part-to-part skew

Applications

• PCI Express interfaces
• FBDIMM applications

Procurement Notes

The 851010AYLFT is classified as an obsolete product. Public documentation indicates it is out of stock. Verification of availability requires checking authorized distributors directly, as inventory status is subject to change and limited supply conditions may apply.

Selection Notes

Select this component when a 1-to-10 fanout buffer converting various differential standards to HCSL is required. Ensure the design accommodates the 3.3V supply voltage and the 0°C to 70°C operating temperature range. Note that the part is obsolete; consider lifecycle implications for new designs.

Part Context

This part belongs to the 851010 series of differential HCSL fanout buffers. It shares functional similarities with other models in the family, such as the 851021, which offers 21 outputs. The 'AYLFT' suffix denotes the TQFP package with tape and reel carrier type.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, alternative components must be identified through independent engineering evaluation.
