Selection of equalization coefficients to configure a communications link between a receiver in a host system and a transmitter in an optical or electrical communication module is performed by a management entity with access to management registers in the receiver and transmitter. Continuous modification of the selected equalization coefficients is enabled on the communications link after the communications link is established to handle varying operating conditions such as temperature and humidity.

A method for improving timing between solid state devices, e.g., in non-volatile memory device is described and includes generating timing signals from the data stream so that the data stream is free from synchronization bits. The PWM data stream is converted from CML to CMOS level. An even decoder decodes the even data signal. An odd decoder decodes the odd signal. The decoders rely on the respective signal, even or odd, to increase past a slower rising signal based on both the odd and even signals to change from a default low state to a high state. The clock signal is derived from edges of the data itself.

Methods and apparatus are described. A method, implemented in a decoder, includes receiving two or more signals from an encoder over two or more respective wires. At least one of the two or more signals includes at least one code that was recoded by the encoder. The decoder receives a recoding table. The recoding table provides a mapping indicating the recoding for each code that was recoded by the encoder in the received two or more signals. The decoder decodes the two or more received signals using the received recoding table.
