85408BGLFT

Overview

The Renesas 85408BGLFT is a single-circuit fan-out clock buffer and driver designed for high-speed signal distribution. It features a 1:8 input-to-output ratio with differential LVDS outputs, supporting maximum frequencies up to 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. Packaged in a 24-TSSOP (0.173 inch width) surface-mount enclosure, it is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Single circuit fan-out buffer with 1:8 ratio
• Differential LVDS outputs supporting 700 MHz max frequency
• Multi-standard input compatibility (HCSL, LVDS, LVHSTL, LVPECL, SSTL)
• 24-TSSOP surface mount package

Applications

• High-speed clock distribution networks
• Data communication equipment requiring low jitter buffering
• Server and storage system timing architectures

Procurement Notes

Verify the specific suffix 'GLFT' against official Renesas documentation to confirm the tape-and-reel packaging format and commercial temperature grade (0°C to 70°C). Cross-reference the part number with current manufacturer status records, as availability data indicates potential discontinuation or end-of-life status for this specific variant.

Selection Notes

Select this component when a single differential input must drive eight LVDS loads at frequencies approaching 700 MHz. Ensure the design environment accommodates the 3.135V to 3.465V supply requirement. Verify that the 0°C to 70°C commercial temperature range meets the target application's thermal constraints, as industrial variants may require different suffixes.

Part Context

This part belongs to the Renesas 85408BG series of clock buffers. It shares core electrical specifications with variants such as the 85408BGILF and 85408BGLF, differing primarily in packaging type (tube vs. tape and reel) and operating temperature range. The 'T' suffix typically denotes tape-and-reel packaging for automated assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate other members of the 85408BG family, such as 85408BGILFT, if industrial temperature ratings (-40°C to 85°C) are required instead of commercial grades.
