It accepts CML, LVDS, LVPECL, or SSTL inputs and delivers ECL or LVPECL outputs, all differential throughout. The part runs from a 2.375 V to 3.465 V supply and handles signals up to 2.1 GHz, making it a fit for telecom line cards, data-center switch fabrics, and test equipment where a clean fanout tree is needed without adding PLL jitter. ## Input and output flexibility The buffer accepts four common differential standards on the input side — CML, LVDS, LVPECL, and SSTL — and outputs ECL or LVPECL. That range means it can sit between a SerDes or FPGA output and multiple downstream receivers without needing external level translation. The 1:4 fanout ratio covers a typical clock-tree branch: one clean source drives four loads, all at the same output swing. ## Package and temperature grade Housed in a 16-VFQFN with exposed pad (3x3 mm body), the part is surface-mount and requires a thermal via pattern under the pad for heat sinking. The operating range spans -40°C to 85°C, covering industrial environments — outdoor base stations, motor-drive backplanes, and uncontrolled telecom cabinets. The exposed pad also improves ground-plane return for the high-frequency signals. ## Lifecycle and sourcing The 8S89831AKILF is listed as Active and ROHS3 compliant.","metaTitle":"8S89831AKILF Fanout Buffer, 1:4, 2.1 GHz, 16-VFQFPN","metaDescription":"Renesas 8S89831AKILF 1:4 fanout buffer distributes CML/LVDS/LVPECL/SSTL inputs to ECL/LVPECL outputs at up to 2.1 GHz.
