85211AMI-01LF

Overview

The 85211AMI-01LF is a clock fanout buffer manufactured by Renesas Electronics Corporation. It provides one-to-two differential signal distribution with a maximum operating frequency of 700 MHz. The device operates on a supply voltage range of 3.135V to 3.465V and accepts multiple input standards including HCSL, LVDS, LVHSTL, LVPECL, and SSTL. Outputs conform to the HSTL standard. It is housed in an 8-SOIC package (0.154 inch width) and supports surface mount mounting. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• 1:2 Differential Clock Fanout Buffer
• Maximum Frequency: 700 MHz
• Multi-standard Input Support (LVDS, LVPECL, HCSL, etc.)
• HSTL Output Standard

Applications

• Clock distribution in high-speed digital systems
• Signal buffering for memory interfaces
• System timing networks requiring differential translation

Procurement Notes

The 85211AMI-01LF is classified as obsolete and is no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or approved substitute components. Ensure that any replacement part matches the original electrical specifications and pinout compatibility before integration into existing designs.

Selection Notes

Select this component when a single differential clock source needs to drive two downstream loads with HSTL-compatible outputs. Verify that the system power supply remains within the 3.135V to 3.465V range. Confirm that the required input signal format is supported by the device's multi-standard input capability. Consider the 8-SOIC package constraints for PCB layout and thermal management.

Part Context

This part belongs to the 85211A family of clock buffers. It serves as a specific variant within Renesas's portfolio of timing solutions designed for high-frequency applications. The device translates various differential input levels to a standardized HSTL output, facilitating interface compatibility across different subsystems in complex electronic architectures.
