IP175B数据手册IC+中文资料规格书

描述 Description

IP175BLF integrates a 5-port switch controller, SSRAM, and 4 10/100 Ethernet transceivers. Each of the transceivers compliers with the IEEE802.3, IEEE802.3u, and IEEE802.3x specifications. The DSP approach is utilized for designing transceivers with 0.16um technology; they have high noise immunity and robust performance.\r
\r
IP175BLF operates in store and forward mode. IP175BLF have a lot of rich feature for different application, include router application, firewall, IEEE 802.1Q, IGMP snooping, policy-based QoS. It provides powerful QoS function, include traffic policy, traffic meter, and flexible queue scheduling (WRR/WFQ/SP). In virtual LAN, IP175BLF support port-based VLAN and IEEE 802.1Q tag-tagged VLAN (up to 16 VLAN groups).\r
\r
IP175BLF support up to 2K MAC addresses, up to 16 VLANs and up to 8 Multi-Field entries. These tables are accessible through MII register. The address table can configure either “2K unicast addresses” or “1K unicast addresses and 1K multicast addresses“. The Multi-Field classification is powerful classifier (layer2 to layer 4 packet headers) in packet classification. The classifier divides incoming packets into multiple classes based on prescribed rules. Each traffic class from classifier can drop out-of-profile packets, monitor traffic, specify forwarding behavior, and specify output queue.\r
\r
Beside a 5-port switch application, IP175BLF supports one MII/RMII ports for router application. The external MAC can monitor or configure IP175BLF by accessing MII registers through SMI0.\r
\r
MII/RMII port also can be configured to be MAC mode. It is used to interface an external PHY to work as 4+1 switch.
