The present invention relates to a coding apparatus for encoding data
represented by 8 bit input symbols into 12 bit output codes for serially
transmitting the codes along a communication channel, the codes being
represented in the channel by signals having a limited minimum and maximum
pulse width and sampled by a receiver at each receiver's clock period. The
invention reduces artifacts introduced by sending data at a higher payload
rate than the bandwidth of the communication channel, such as the voltage
and current offsets introduced in the data at the receiver as a function
of the preceding data.
