85314BMI-01LF

Overview

The 85314BMI-01LF is a clock driver and distribution component manufactured by Renesas Electronics. It functions as a five-output LVPECL buffer, designed to distribute clock signals with high integrity. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 20-pin SOIC package. This part belongs to the 85314I-01 series and is identified by the alias ICS85314BMI-01LF. The component is currently listed as obsolete or end-of-life.

Feature Summary

• Five differential LVPECL outputs for clock distribution
• Low skew performance suitable for high-speed digital systems
• Operates over extended industrial temperature range (-40°C to +85°C)
• Available in standard SOIC-20 surface mount package

Applications

• High-speed data communication equipment
• Server and storage system clock distribution
• Test and measurement instrumentation

Procurement Notes

This component is classified as obsolete or end-of-life by the manufacturer. Availability is limited to existing stock from third-party distributors. Buyers should verify the authenticity of sources and check for potential product change notices. Last-time buy options may have expired. Ensure compatibility with current design requirements before sourcing surplus inventory.

Selection Notes

Engineers replacing this part should consider the specific LVPECL output configuration and the five-channel fan-out requirement. Verify that alternative components match the 20-pin SOIC footprint and electrical characteristics. Since the original part is obsolete, evaluate newer generations from the same family or competitive equivalents that offer similar skew and propagation delay specifications.

Part Context

The 85314BMI-01LF is part of the 85314I-01 series of clock buffers. It serves as a legacy solution for distributing low-voltage positive emitter-coupled logic (LVPECL) signals. The 'BMI' suffix typically denotes the package type and temperature range, while 'LF' indicates lead-free compliance. It was commonly used in systems requiring precise clock synchronization across multiple receivers.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in public documentation. Engineers must evaluate functional equivalents that provide five LVPECL outputs with comparable skew specifications. Check for updated datasheets from Renesas or other manufacturers offering modern alternatives with improved availability.
