DALLAS Texas Instruments Inc. has introduced two new ThunderSwitch II single-chip switching devices for Fast Ethernet and Gigabit Ethernet applications.
The first, TNETX4080, is an eight-port device for low-cost (less than $10 per port) Ethernet 10/100 performance in small-office networks requiring no more than 50 ports.
It includes an integrated management port, so designers can create inexpensive unmanaged products as well as value-added, managed products.
The second single-chip device, TNETX4020, is for high-demand network uplinks and switches.
It has two ports that each deliver 1-Gbit/second switching with non-blocking operation and it can be used to create a gigabit uplink for Ethernet switches or to create switches that offer multigigabyte performance. Multiple devices can be connected in a cascade-ring mode.
The TNETX4020 is designed to work with TI's TNETX4090 10/100/1,000-Mbit/s switch device.
The TNETX4080 in a 352-ball grid array is priced at $55 in 10,000-unit quantities. The TNETX4020 in a 208-pin quad flat pack sells for $90 in 10,000-unit quantities.
