FEATURES
• Monolithic intelligent Gigabit Ethernet Switch Port Controller.
• Integrates an IEEE 802.3z-compatible Gigabit MAC.
• May be used alone or in combination with other devices to build 10/100 or Gigabit switches.
• Supports the Gigabit EXACT™ Bus Protocol for device interconnect.
• May be used alone or in combination with other device to build high density Gigabit switches.
• PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 16 Gigabit ports.
• Layer 2 line rate address lookup capability for all Ethernet port configurations supported.
• Store-and-forward switching using output association input buffering for efficient memory use without Head Of Line (HOL) blocking.
• Supports up to 8,000 MAC addresses.
• 1022 multicast groups available. Bitmask per group defines membership.
• EXACT Bus is compatible with common serial devices for simple system stacking using coax or twinax cable.
• Support for IEEE 802.1D bridging and spanning tree algorithm in an external processor.
• Embedded SmartPath™ Processor supports value-added datapath operations.
• Two 32-bit memory interfaces for flexible combinations of SSRAM and EPROM allow cost optimization of different applications.
• Programmable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types. MANAGEMENT
• System Interface provided in CMI to support standard SNMP software packages, or the porting of existing management software.
• Hardware statistics collection supports RMON-I (nine groups), Ethernet MIB, and SNMP agent functions.
• All statistics registers and data structures accessible through the CMI.
• Supports the implementation of Spanning Tree (IEEE 802.1D) by exchanging BPDU packets on all ports.

APPLICATIONS
• Gigabit Ethernet Switches.
• Ethernet Switching Systems Capable of 10, 100, and 1000 Mbit/s Operation When Used with PM3370 and PM3390.
• Gigabit Test Equipment.
