The HOTLink family of devices transfers data from point to point over high-speed serial links at 160 to 330 Mbits/second (Figure 1). The CY7B923 Transmitter (Figure 2) takes an 8-bit parallel data stream and encodes it using the Fibre Channel compliant and ESCON™-compliant 8B/10B code. This code maps all 8-bit data characters into a 10-bit transmission code that insures the transmission signal contains suitable transitions for recovery by the receiving device. The transmitter takes this 10-bit data word and converts it to a serial bit-stream and transmits it at 10 times the byte rate over a serial transmission link.
