General Description
Encoder/Decoder pair that implements the standard IBM® 8b/10b line code for a DC-balanced serial data stream. The 8b/10b code is a common encoding scheme used for the transmission of serial AC-coupled data with embedded clock over larger distances.
Key Design Features
– Supports the standard IBM® 8b/10b line code for a DC-balanced serial data stream
– Supports all standard control symbols – K.28.0 to K.30.7
– Separate encoder and decoder pair
– Fully synchronous design with data input and output valid flags
– Generic parallel input and output data widths
– Error flags indicate control symbol errors and general decoding errors
– Running disparity calculations handled internally and provided as an output port
– Fully scalable architecture
– Suitable for use in serial data links of 6 GHz+ on basic FPGA devices
Applications
– High speed serial interfaces with embedded clocking
– DC-balanced, AC-coupled serial interfaces
– Prerequisite for the transmission of serial data over large distances
– Encoding scheme used in a wide range of communication standards
– Examples include: Ethernet, PCI Express, DVB-ASI, Digital audio, Fibre Channel etc.
