8S89831AKILF

Clock Buffers, Drivers Overview

The 8S89831AKILF is a clock fanout buffer manufactured by Renesas Electronics. It operates with a single input and provides four differential outputs, achieving a 1:4 distribution ratio. The device supports maximum frequencies up to 2.1 GHz. It utilizes LVPECL input signals and converts them to either LVPECL or ECL output formats. The component is housed in a 16-VFQFN package with an exposed pad for thermal management.

Clock Buffers, Drivers Feature Summary

• Provides high-speed 1:4 clock signal distribution
• Converts differential LVPECL inputs to LVPECL or ECL outputs
• Supports operation at frequencies up to 2.1 GHz

Clock Buffers, Drivers Applications

• High-speed data transmission systems
• Telecommunications infrastructure equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific output voltage level configuration required for the target application, as the datasheet indicates support for both LVPECL and ECL output types. Confirm that the supply voltage and termination resistors align with the selected output standard to ensure signal integrity. Check current availability status through authorized distributors due to potential supply chain fluctuations.

Clock Buffers, Drivers Selection Notes

Select this component when a single high-frequency clock source must be distributed to four separate loads requiring LVPECL or ECL signaling. Ensure the system design accommodates the thermal requirements of the VFQFN package. Compare against other Renesas buffers if lower frequency or different output logic families are needed.
