• May be used alone or in combination

with other devices to build 10/100 or

Gigabit switches.

Spanning Tree (IEEE 802.1D) by

exchanging BPDU packets on all ports.

• Customer product differentiation is

enabled by applications using CMI

calls to leverage EXACT system

resources.

VLAN

• Supports the Gigabit EXACT™ Bus

Protocol for device interconnect.

• Up to 4094 IEEE 802.1Q VLAN tags

with support for 4094 FIDs.

COMPATIBILITY

EXACT Bus Switch Matrix.

• PM3390 EXACT Bus Switch Matrix

allows non-blocking expansion up to

16 Gigabit ports.

• GARP, GVRP, GMRP packet

identification and forwarding to

external CPU for processing.

PACKAGING

• Layer 2 line rate address lookup

capability for all Ethernet port

configurations supported.

• Provides a standard five signal

P1149.1 JTAG test port for boundary

scan board test purposes.

• Tag insertion and removal for unicast

and multicast packets.

• Store-and-forward switching using

output association input buffering for

efficient memory use without Head Of

Line (HOL) blocking.

• Implemented in low power 3.3 V,

CMOS technology with 5 V tolerant MII

interface.

PRIORITY
