85408BGLF

Overview

The Renesas 85408BGLF is a single-channel fan-out clock buffer designed for signal distribution. It features a 1:8 input-to-output ratio with differential LVDS outputs and supports multiple input standards including HCSL, LVDS, LVHSTL, LVPECL, and SSTL. The device operates at a maximum frequency of 700 MHz with a supply voltage range of 3.135V to 3.465V. It is housed in a 24-TSSOP package (0.173 inch width) and is rated for commercial temperature operation from 0°C to 70°C.

Feature Summary

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

Applications

• Clock distribution networks
• Signal buffering and driver applications
• High-speed digital systems requiring low skew distribution

Procurement Notes

Verify the specific suffix requirements for your design, as the 'ILF' variant denotes industrial temperature range (-40°C to 85°C) while the 'GLF' is commercial grade (0°C to 70°C). Confirm current product status, as listings indicate this component may be discontinued or subject to availability constraints. Ensure the 24-TSSOP footprint matches your PCB layout specifications.

Selection Notes

Select the 85408BGLF when a commercial temperature range (0°C to 70°C) is sufficient for the application environment. Choose this part over the 85408BGILF if cost optimization is prioritized over extended thermal tolerance. Verify that the required input signal standard is compatible with the device's multi-standard input capability and that the 3.135V to 3.465V supply voltage aligns with the system power rails.

Part Context

This component belongs to the Renesas 85408B series of clock buffers. It shares core electrical characteristics with variants such as the 85408BGILF, differing primarily in operating temperature range and packaging format. The series is designed for high-frequency clock distribution tasks within electronic systems.

Replacement Considerations

The 85408BGILF serves as a direct functional substitute with an expanded industrial temperature range (-40°C to 85°C). Ensure the replacement meets the thermal requirements of the final assembly before swapping.
