85311AMLF

Overview

The Renesas 85311AMLF is a low skew, high performance differential-to-differential fanout buffer. It translates one differential input signal to two differential LVPECL outputs. The device operates from a single 3.3V supply (2.375V to 3.465V) or a dual supply configuration. It supports input levels including LVDS, LVPECL, and SSTL. The component is characterized for operation over an ambient temperature range of 0°C to 70°C. It is housed in an 8-pin SOIC package.

Feature Summary

• Translates one differential input to two differential LVPECL outputs
• Accepts LVDS, LVPECL, and SSTL input levels
• Low skew characteristics with typical output skew of 25ps
• Operates on a single 3.3V supply voltage

Applications

• Clock distribution networks requiring differential translation
• High-speed data acquisition systems
• Telecommunications equipment clocking

Procurement Notes

Verify the obsolete status of the 85311AMLF before procurement planning. Check for active replacement components within the Renesas portfolio that maintain pin compatibility and electrical specifications. Confirm RoHS compliance details through official documentation as legacy parts may have specific environmental declarations.

Selection Notes

Select this component when a single differential source must drive two LVPECL loads with minimal skew. Ensure the design accommodates the 0°C to 70°C operating temperature range. Verify that the input signal levels match the supported LVDS, LVPECL, or SSTL standards. Consider the 8-pin SOIC package constraints for PCB layout.

Part Context

The 85311 belongs to the ICS8531 family of clock buffers. This series focuses on low jitter and low skew performance for high-speed digital applications. The AM suffix typically denotes the commercial temperature grade and package variant within the product line.

Replacement Considerations

Consult Renesas technical resources for direct replacements. The 85311I-01 is a related industrial-grade variant. Verify if newer generation buffers offer improved skew or power efficiency while maintaining the same footprint.
