ABSTRACT:
An integrated circuit like a programmable logic device (“PLD”) includes a communication channel employing 8B/10B coding. Disparity information determined by 8B/10B decoder circuitry in the communication channel is supplied to other circuitry of the PLD so that any requirement for disparity to have a particular value in conjunction with certain received codes can be checked. On the transmitter side, circuitry is provided for selectively forcing the 8B/10B encoder to use a commanded disparity (which can be either positive or negative) under particular circumstances.
