85211AMI-03LF

Overview

The 85211AMI-03LF is a 1-to-21 Differential HCSL Fanout Buffer designed to translate various differential input signal levels, including LVPECL, LVHSTL, LVDS, and HCSL, into differential HCSL output levels without requiring external bias networks. Operating at a maximum frequency of 250MHz, the device features twenty-one differential outputs with an output skew of 395ps (maximum) and part-to-part skew of 335ps (maximum). It is characterized for operation at a supply voltage of 3.3V and supports ambient temperatures from 0°C to 70°C.

Feature Summary

• Translates any differential input signal (LVPECL, LVHSTL, LVDS, HCSL) to HCSL levels without external bias networks
• Provides twenty-one differential HCSL outputs with a maximum output frequency of 250MHz
• Features low timing jitter characteristics with an output drift of 140ps (maximum)
• Operates on a full 3.3V supply voltage in lead-free packages

Applications

• PCI Express interface applications
• FBDIMM memory system interfacing
• Clock distribution in high-speed digital systems

Procurement Notes

Verify component status as the 85211AMI-03LF may be obsolete or discontinued. Confirm package type, pin count, and moisture sensitivity level against current inventory requirements. Check for available replacement options if new production is planned.

Selection Notes

Select this buffer when translating multiple differential clock sources to HCSL standards for PCI Express or FBDIMM applications. Ensure the design accommodates the 3.3V supply requirement and the specific skew specifications (395ps max output skew) required by the target interface timing constraints.

Part Context

This component belongs to the family of differential fanout buffers used for clock signal conditioning. It serves as an interface between various differential signaling standards and HCSL loads, commonly found in server and storage architectures requiring precise clock distribution.

Replacement Considerations
