AMCC Offers Quad SONET/SDH Phys for System "Face-lifts"

Applied Micro Circuits Corp. (AMCC) introduced two new quad SONET/SDH physical layer devices designed for new high density line cards as well as the remodeling of legacy line cards. For reworking earlier system designs, the new quad OC3/12 SONET/SDH 8-bit transceiver requires only that customers update the optical front-end of the design, while the rest of the system, such as the framers, pointer-processors and software, can remain intact.


The first device (S1213) operates in either SONET/SDH OC-12 or OC-3 with a CDR feature, and can also be provisioned to support a combination of OC-3 and OC-12 data for individual channels. Features including diagnostic loopback, line loopback, serial clock loop timing and parallel loop back modes. It also provides customers with maximum flexibility and efficiency when adding new components to legacy systems.


The second device (S1212) consists of four CDR modules, all of which can run independently at the OC-12 or OC-3 data rate. It can also be provisioned to mix and match OC-3 and OC-12 data streams within the same device and configured in MII mode or non-MII mode. http://www.amcc.com
