85408BGILF

Overview

The Renesas 85408BGILF is a single-channel fan-out clock buffer and driver designed for high-speed signal distribution. It features a 1:8 input-to-output ratio, supporting up to eight differential outputs. The device operates with a maximum frequency of 700 MHz and accepts multiple input standards including HCSL, LVDS, LVHSTL, LVPECL, and SSTL, while providing LVDS-compatible outputs. It functions within a supply voltage range of 3.135V to 3.465V and is rated for an industrial operating temperature range of -40°C to 85°C. The component is housed in a 24-TSSOP package with a width of 4.40mm.

Feature Summary

• Single channel configuration with 1:8 fan-out ratio
• Supports HCSL, LVDS, LVHSTL, LVPECL, and SSTL inputs
• Maximum operating frequency of 700 MHz
• Industrial temperature range (-40°C to 85°C)

Applications

• High-speed clock distribution networks
• Server and storage system timing architectures
• Telecommunications equipment synchronization

Procurement Notes

Verify the specific suffix 'ILF' against official Renesas documentation to confirm the exact temperature grade and packaging type, as variations exist within the 85408B family. Confirm current product status, as this part number may be discontinued or subject to last-time-buy restrictions based on manufacturer updates.

Selection Notes

Select this component when a single differential input must drive eight LVDS loads at frequencies up to 700 MHz. Ensure the design accommodates the 3.135V to 3.465V supply requirement and the 24-TSSOP footprint. Verify that the source signal matches one of the supported input standards (HCSL, LVDS, etc.).

Part Context

The 85408BGILF belongs to the Renesas 85408B series of clock buffers. This series provides flexible interface options for various logic families. The 'I' suffix typically denotes the industrial temperature range, distinguishing it from commercial variants like the 85408BGLF which operates from 0°C to 70°C.
