8B/10B Encoder
Each channel contains an 8B/10B encoder which translates the 8-bit input data on Tn(7:0) into a 10-bit
encoded data character. C/Dn inputs are also provided in each channel which, along with KCHAR, allow the
transmission of special Fibre Channel Kxx.x characters (see Table 3). Note that KCHAR is a static input, and
does NOT have the same input timing as Tn(7:0), C/Dn and WSENn. Normally C/Dn is LOW in order to
transmit data. If C/Dn is HIGH and KCHAR is LOW, then a Fibre Channel defined IDLE Character (K28.5 =
‘0011111010’ or ‘1100000101’ depending on disparity) is transmitted and Tn(7:0) is ignored. If C/Dn is HIGH
and KCHAR is HIGH, a Kxx.x character is transmitted as determined by the data pattern on Tn(7:0) (see Table
4). Data patterns other than those defined in Table 4 produce undefined 10B encodings.
