COMPARING THE TNETX15VE AND TNETX15AE EALE DEVICES

This application brief highlights the operational differences between the Texas Instruments (TIä) TNETX15VE and TNETX15AE Address Lookup Engine (EALE) devices. The EALE devices supplement the internal address handling capabilities of TI ethernet switch devices.

Both the TNETX15VE and TNETX15AE are based on a table lookup but include diverse design features targeted for different market segments. The TNETX15AE handles a large address pool but lacks the controls required to implement Spanning Tree and VLAN. The TNETX15VE supports a smaller address pool but adds the necessary control structure for Spanning Tree and VLAN.
