description

The TNETX15VE performs the VLAN-engine address-lookup function for the TNETX3150/TNETX3150A

Ethernet switch using a glueless interface. The TNETX15VE device determines the addresses to use and

match from the TNETX3150/TNETX3150A DRAM bus. The address-lookup table is maintained in external

SRAM. The frame-matching and routing information is given to the TNETX3150/TNETX3150A through the

external address-matching (EAM) interface.

The TNETX15VE is designed to work in either unmanaged or managed mode. Unmanaged operation is

accomplished through EEPROM support. Startup options are auto-loaded into the TNETX15VE registers using

the EEPROM interface. If the TNETX15VE is initialized by automatic loading from the EEPROM, it begins

operation automatically.

All functions of this device are fully controllable by management through a direct input/output (DIO) interface.

In addition, this device can interrupt the external management processor with user-selectable interrupts.

This device also provides support for easy management control of IEEE Std 802.3u media-independent

interface (MII) managed devices. A typical application is shown in the following:
