Flexible high speed forward error correction (FEC) physical medium attachment (PMA) and physical coding sublayer (PCS) connection system

摘要

Systems, methods, apparatus, and techniques relating to a transmitter interface are disclosed. A soft-IP transmitter interface includes a Reed-Solomon encoder operating according to any one of multiple bus width and bandwidth parameter pairs, and a gearbox module that includes multiple gearboxes. The multiple gearboxes receive input data at a bus width and clock rate parameter pair specified by the soft-IP transmitter interface and convert the input data into output data according to a number of physical lanes and bandwidth parameter pair specified by a physical medium attachment (PMA) standard.
