TC9208M

TC9208M Preliminary Data Sheet 8-Port 10/100/1000 Smart Ethernet Switch Features Stand Alone Switch On A Chip 8 Ethernet 10/100/1000 ports MII/GMII interface for all ports Trunk group support Four Classes of Service (CoS) selectable for each port and/or checked via IP Header and 802.1Q VLAN Tag Eight port-based VLANs Maximum throughput, non head-of-line blocking architecture Embedded SSRAM packet buffer/address table 8K MAC address table Each port is configurable to 10 full/half duplex, 100 full/half duplex and 1000 full duplex mode Flow-control ability is able to set for both full and half duplex mode Broadcast throttling Port Mirroring Serial EEPROM Interface, EEPROM is optional MDIO master for PHY configuration / polling 0.18 micron technology 2V and 3.3V dual voltage power supply Packaged in PBGA 292 27 MHz crystal input only This feature allows improved multimedia applications. support for The chip embeds IEEE 802.3 MAC functions for each port and these functions support full and half duplex modes for both 10 and 100 Mbits/s data rates and full duplex for 1000 Mbit/s. Each port includes dedicated receive and transmit FIFOs with necessary logic to implement flow control for both full and half duplex modes. TC9208M uses IEEE 802.3x frame based flow control for full duplex and backpressure for half duplex. TC9208M handles an 8K address-lookup table with searching, self-learning, and automatic aging, at very high speed and excellent address space coverage. Forwarding rules...
