85311AMILF

Overview

The ICS85311AMILF is a low skew, 1-to-2 differential-to-2.5V/3.3V LVPECL/ECL fanout buffer manufactured by Renesas Electronics Corporation. It operates with a supply voltage range of 2.375V to 3.8V and supports maximum frequencies up to 2.5 GHz. The device features differential inputs compatible with CML, LVDS, LVPECL, and SSTL standards, providing two differential LVPECL or ECL outputs. It is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm) and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Provides low skew signal distribution for high-speed differential clock applications
• Accepts multiple input standards including CML, LVDS, LVPECL, and SSTL
• Generates dual differential LVPECL or ECL output signals
• Ensures precise timing performance through guaranteed part-to-part skew characteristics

Applications

• High-speed data communication systems requiring precise clock distribution
• Server and storage infrastructure clocking networks
• Telecommunications equipment utilizing differential signaling standards
• Test and measurement instruments demanding low jitter performance

Procurement Notes

Verify the specific suffix 'AMILF' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the operating environment remains within the specified -40°C to +85°C range. Confirm that the system power supply strictly adheres to the 2.375V to 3.8V limits to prevent device malfunction. Validate input signal compatibility with the supported CML, LVDS, LVPECL, or SSTL levels before integration.

Selection Notes

Select this component when a single differential source must drive two distinct loads with minimal skew variation. It is suitable for designs requiring support for various differential input standards without level shifting circuitry. Consider the 8-SOIC package constraints for board space. This device is appropriate for applications where deterministic timing and low additive phase noise are critical requirements for system stability.

Part Context

The ICS85311 belongs to the Renesas family of high-performance clock buffers and drivers. It succeeds earlier integrated circuit technologies focused on differential fanout solutions. The device maintains compatibility with industry-standard differential signaling protocols used in modern high-speed digital interfaces. It serves as a key building block for distributing reference clocks across complex multi-component electronic systems.

Replacement Considerations

The ICS853011CMLFT is a documented functional substitute offering identical 1-to-2 differential fanout capabilities and similar electrical specifications. Verify pinout compatibility and ensure the replacement variant meets the same thermal and voltage requirements.
