MU9C8358L中文资料MUSIC数据手册PDF规格书

GENERAL DESCRIPTION

The MU9C8358L, when configured with MUSIC Semiconductors MU9Cx480B family of LANCAMs, provides a high performance, large capacity Ethernet address processing subsystem for use in Ethernet bridge, switch, or remote access products. The device is designed to work in multi-port systems that require a common address database for all ports. Built-in arbitration allows two MU9C8358L devices to share a common CAM database, supporting up to eight 100Mb/s Ethernet ports at wire speed.
