Product Summary

The PM3370-BCGP is an Octal 10/100 Mbit/s Switch Port-Controller. The applications of the PM3370-BCGP include Ethernet Switching System Requiring High Density 10/100 Ports, Ethernet Switching Systems Capable of 10, 100, and 1000 Mbit/s Operation When Used with PM3380 and PM3390.

Features

PM3370-BCGP features: (1)Monolithic intelligent octal 10/100 Ethernet Switch Port Controller; (2)Integrates eight 10/100 MACs that connect to physical layer devices over standard IEEE 802.3u MIIs; (3)Supports the Gigabit EXACT Bus Protocol for device interconnect; (4)May be used alone or in combination with other devices to build high density 10/100 switches; (5)PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 96 10/100 Mbit/s ports; (6)Layer 2 line rate address lookup capability for all Ethernet port configurations supported; (7)Store-and-forward switching using output associated input buffering for efficient memory use without Head Of line (HOL) blocking; (8)Supports 8,000 MAC addresses; (9)1022 multicast groups available. Bitmask per group defines membership.
