PM5309
Overview
- 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.
