Power optimization mechanisms for framers by serializing frame alignment processes for multiple lanes

A receiver in a telecommunication system, the receiver comprises:

• an input interface configured to receive data streams associated with a plurality of channels, wherein each data stream comprises a plurality of frames, and wherein each frame of said plurality of frames comprises same frame alignment information;
• and
• a framer coupled to said input interface and configured to process said plurality of channels sequentially to perform frame alignment with respect to said plurality of channels, wherein said frame is configured to process a single channel one at a time, and wherein performing frame alignment on said data stream comprises:
• determining whether frame alignment is achieved for a channel that is last processed by said framer;
• and
• detecting a location of said same frame alignment information in said data stream.

A method of performing frame alignment at a receiver, the method comprising:

• receiving a first plurality of data streams at an input of said receiver, wherein a respective data stream is transmitted through a respective physical lane d comprises a plurality of frames, and wherein each frame comprises a fray - alignment word;
• and
• successively processing said first plurality of data streams when perform frame alignment on said first plurality of data streams by using a framer, wherein said successively processing comprises:
• said framer processes one data stream at a time;
• and determining whether frame alignment is achieved for a data stream that is last processed by said framer, and wherein said first plurality of data streams are associated with a same channel, and wherein performing frame alignment on said respective data stream comprises detecting a location f said frame alignment word in said respective data stream.
