858S011AKILFT

Overview

The Renesas 858S011AKILFT is a low skew, 1-to-2 differential-to-CML fanout buffer designed for high-speed clock distribution. It accepts differential CML or LVDS inputs and provides two complementary CML outputs. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports data rates up to 2.5 GHz. It functions reliably across an industrial temperature range of -40°C to +85°C. The component is housed in a 16-VFQFN exposed pad package with a 0.5 mm pitch.

Feature Summary

• Provides low skew signal distribution from one differential input to two complementary CML outputs
• Supports multiple input logic standards including CML and LVDS for flexible system integration
• Optimized for high-speed operation with minimal propagation delay variations

Applications

• High-performance server and storage system clock distribution
• Telecommunications infrastructure timing networks
• Test and measurement equipment requiring precise clock synchronization

Procurement Notes

Verify the specific suffix 'FT' indicates tape and reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official datasheets. Ensure the ordering part number matches the exact package type and lead-free specifications required for your assembly process. Cross-reference the full part number against current Renesas product status to confirm availability.

Selection Notes

Select this component when a single differential source must drive two distinct CML loads with minimal skew. It is suitable for applications requiring LVDS or CML input compatibility. Consider the 16-VFQFN package constraints for PCB layout. Verify that the operating voltage and temperature ranges align with the target system environment before implementation.

Part Context

This part belongs to the Renesas 858S011I series of clock buffers. It is specifically engineered for differential-to-CML conversion tasks. The series focuses on maintaining signal integrity in high-frequency digital systems. It complements other Renesas timing solutions by providing dedicated fanout capabilities for complex clock trees.
