The Precise-ITC Scalable Serdes Framer Interface Digital Core IP implements the digital portion of the SFI-S interface (OIF-SFI-S-01.0). The SFI-S interface is used to connect communication microchips with 80-160 Gbps or higher bit-rate. It is a scalable interface which can support 4 – 20 lanes and each lane can have bit-rate over 6.25 – 11.2 Gbps.
It features an efficient design with a small footprint, minimizing device resource requirements and lowering component costs.
