851010AYILF

Overview

The 851010AYILF 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. The device operates at a maximum output frequency of 250MHz with 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 maximum high-level output voltage (VOH) is 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 without external bias networks
• Maximum output frequency of 250MHz
• Full 3.3V supply voltage operation

Applications

• PCI Express interfaces
• FBDIMM applications

Procurement Notes

The 851010AYILF is listed as an obsolete product. Verification of availability requires checking authorized distributors for remaining stock or alternative sourcing channels. Confirm the specific suffix 'AYILF' matches the required package and lead-free status against current inventory records, as general model listings may not reflect exact suffix variations.

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 and 0°C to 70°C temperature range. Verify that the 165ps output skew and 250ps part-to-part skew meet the system timing requirements for PCI Express or FBDIMM implementations.

Part Context

The 851010AYILF belongs to the 851010 series of clock buffers. It shares functional characteristics with other models in the family, such as the 851021, which offers 21 outputs. The 'AYILF' suffix typically denotes a specific package type (TQFP) and lead-free (RoHS compliant) construction, distinguishing it from non-compliant or differently packaged variants within the same product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineers should evaluate newer Renesas clock buffer families or generic 1-to-10 HCSL fanout buffers with compatible pinouts and electrical specifications.
