Routing Control, Monitoring and Policing 800Mbit/s

• Monolithic single chip device which handles ATM switch Ingress VPI/VCI address translation, cell appending, cell rate policing, counting, and OAM requirements for 65,536 VCs (virtual circuits).
• Instantaneous transfer rate of 800 Mbits supports a cell transfer rate of 1.42x106 cells/s.
• 8 or 16 bit PHY interface using direct addressing for up to 4 PHYs (Utopia Level 1) and Multi-PHY addressing for up to 32 PHYs (Utopia Level 2).
• 8 or 16 bit SCI-PHY+ (53 - 64 byte extended ATM cell with prepend/postpend) interface at output to switch fabric.
• Compatible with wide range of switching fabrics and traffic management architectures including per VC or per PHY queuing.
• Provides identification/tagging of RM cells to support adjunct processing applications such as Virtual Source/Virtual Destination ABR service.
• Supports logical multicast.
• Extremely flexible CAM-type cell identification which uses arbitrary VPI/VCI values and/or appended bytes for identification.
• Drops on command all low priority (CLP=1) cells to relieve switch congestion.
• Includes 16-bit FIFO buffered microprocessor bus interface for cell extraction and insertion (including OAM), VC table access, control and status monitoring, and configuration of the IC.
• Supports DMA access for cell extraction and insertion.
• Low power, 0.6 micron, +5 Volt CMOS technology.
