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. 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 forming a PDU for transmission over the link. 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.
