Systems and methods for enabling data transfers over communications links having a plurality of transmission lanes. In one embodiment, a system comprises a plurality of elastic buffers, each of which is coupled to one of the lanes in the communications link, and a buffer controller coupled to the buffers. Data is clocked into the elastic buffers using a first clock signal and is clocked out of the buffers by a second clock signal. The buffer controller is configured to monitor each of the buffers and to detect impending underflow or overflow conditions. In response to detect in one of these conditions, the buffer controller will cause the words to be added or deleted, respectively, to all of the elastic buffers rather than only the buffer in which the overflow/underflow condition was detected.
