Patent ID: 8199782

Claim:
A system for detecting skew across a plurality of transmitting lanes in a high-speed data transmission system, the system comprising: a communication circuitry; (a) a plurality of data transmitted by the communication circuitry as a plurality of frames across the plurality of transmitting lanes, wherein each of said plurality of transmitting lanes is coupled to one of a plurality of framers; (b) a frame start signal detected in said plurality of data by said plurality of framers, wherein said frame start signal indicates a starting bit of each of said plurality of frames; and (c) a frame synchronization signal detected in said plurality of frames by said plurality of framers, wherein said frame synchronization signal indicates an origin of each of said plurality of transmitting lanes in said plurality of data, wherein the system detects skew between said plurality of transmitting lanes using the frame start signal and the frame synchronization signal.
