Rapid I/O 2.2 spec

pkm_ind

The RapidIO 10xN specification is in development now and is backward compatible with the RapidIO Gen1 and Gen2 systems that are being deployed in the market today. Initially, the RapidIO 10xN specification will support 10 Gbaud per serial lane with lane widths up to x16, resulting in data rates up to 160 Gbps per port direction. The RapidIO 10xN set of specifications will also scale to serial lane speeds of 25 Gbps and beyond as there are no limitations in the logical and transport layer, thus allowing for the standard to keep in lock step with main stream PHY technology.  Protocol efficiency is further improved by the use of industry leading coding scheme that moves from the 25% overhead of 8b/10b encoding to schemes that have less than 5% encoding overhead
