В Xilinx есть Aurora, в Altera есть SerialLite II/III. Это уже готовые корки и протоколы для быстрого LVDS точка-точка.
Цитата
The SerialLite II protocol, like its predecessor, is defined as a lightweight point-to-point serial interconnect with low protocol overhead, minimal data transfer latency, and a range of optional features to minimize logic requirements for the most cost-effective implementations.
SerialLite defined a full-duplex protocol based on a 16-bit datapath width (per lane), which resulted in minimal logic consumption for applications requiring symmetrical (transmit and receive) lane widths with lane rates from 1.6 to 3.125 Gbps.
SerialLite II builds on the success of SerialLite with optimized support for simplex, asymmetric, and broadcast data flows, and extended scalability with optional datapath widths (8-, 16-, or 32-bit per lane) for optimal implementations of lane rates below 1.5 Gbps and up to 6.375 Gbps.
