Multi-rate Telecom Backplane SERDES for 2.5 Gbit/s Interconnect
FEATURES
High performance backplane interface and cross-connect for 2.5G line cards in SONET/SDH systems. Provides one low-speed parallel TelecomBus interface operating at 32 bits x 77.76 MHz. Provides three high-speed multi-rate serial backplane interfaces. Supports CLOS and memory-based switch fabric systems. Supports linear, UPSR, and BLSR protection strategies. Provides two pages of connection memory with software and hardware controlled hitless page swaps at frame boundaries. Provides integrated delay management that allows for arbitrary SONET/SDH frame alignments on each ingress serial link. High-speed serial RASIO compatible with CML, LVDS, and LVPECL. Supports nibble and di-bit slicing on 622 Mbit/s links for sliced switching architectures.
