8T79S818A-08NLGI8

Clock Buffers, Drivers Overview

The 8T79S818A-08NLGI8 is a high-performance clock buffer manufactured by Renesas Electronics Corporation. It functions as a fanout buffer, divider, and multiplexer with a 1:8 input-to-output ratio. The device accepts differential LVDS or LVPECL inputs and provides corresponding LVDS or LVPECL outputs. It supports maximum frequencies up to 1.5 GHz and operates on a supply voltage range of 2.375V to 3.465V. Designed for surface mount assembly, it is housed in a 32-VFQFN exposed pad package (5x5 mm) and rated for an ambient operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Procurement Notes

This component is available in Tape & Reel packaging. Verify the specific ordering suffix against official Renesas documentation to ensure correct package type and tape configuration. Confirm current availability status directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS directives if required for the target application environment.

Clock Buffers, Drivers Selection Notes

Select this part when a 1:8 differential fanout is required with LVDS or LVPECL compatibility. Ensure the system power supply falls within the 2.375V to 3.465V range. The 32-VFQFN package requires appropriate PCB thermal management due to the exposed pad design. Verify that the 1.5 GHz maximum frequency meets the specific clock speed requirements of the downstream components.

Clock Buffers, Drivers Part Context

The 8T79S818A-08NLGI8 belongs to the Renesas 8T series of clock buffers. This series is characterized by high-frequency operation and flexible output configurations. The '8' in the model number typically denotes the 1:8 output ratio, while the 'A' suffix often indicates a specific revision or pin-compatible upgrade within the family. It serves as a critical interface component for distributing reference clocks in complex digital systems.

Clock Buffers, Drivers Replacement Considerations

Consult Renesas official cross-reference lists for verified substitutes. Generic clock buffers may not match the specific LVDS/LVPECL electrical characteristics or the 1.5 GHz performance limit. Ensure any replacement maintains the 32-VFQFN footprint and compatible supply voltage ranges.
