As a result of the increasing complexity of electronic chips, the bandwidths required for inter- and intra-chip communication are rapidly increasing. As optoelectronics provides high-bandwidth and high-density interconnection it is considered as a candidate for short-range interconnection. For such interconnections, situated at a low level in the systems hierarchy, the interconnect latency is extremely critical for the systems performance. This paper describes some methods for mesochronous synchronization, needed for such interconnections. It will be shown that it can be beneficial to use an additional optical link to transfer a synchronization signal. Such a reference signal can be used efficiently for phase detection, provided that the data skew is sufficiently small, and result in a decrease of the cost-per-link.
