Multi-rate Telecom Backplane SERDES for 2.5 Gbit/s Interconnect
FEATURES
• Provides two pages of connection
• High-speed serial RASIO compatible
• 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.
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.
SERIAL PORT FUNCTIONS
with CML, LVDS, and LVPECL.
• Supports nibble and di-bit slicing on
622 Mbit/s links for sliced switching
architectures.
PARALLEL PORT FUNCTIONS
