Abstract
Embodiments of the invention provide improved timing compensation for a bidirectional serial link in order to relax accuracy requirements of clock sources used for the link. When forming a Protocol Data Unit (PDU) for transmission over the link, fill levels of receiver buffers at either ends of the link are used to determine a particular type of start of PDU (SOP) character sequence to use. When a given type of SOP character sequence is present in a PDU received at one end of the link, a next PDU to be transmitted from the same end of the link is delayed by a predetermined amount of time to allow the receiver buffer at the other end of the link to decrease its fill level before receiving the next PDU.
