Texas Instruments Introduces a High-Performance LAN Switch Supporting Gigabit Ethernet LAN Switching

TS3L301 Provides Wide Bandwidth Suitable for 10/100/1000 Mbit Ethernet Signaling

Mar 22, 2005

DALLAS (March 22, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) unveiled today its first LAN switch that supports Gigabit Ethernet LAN Switching. With the majority of Notebook PCs on today´s market requiring a method of switching Gigabit Ethernet LAN signals to a docking station, as well as Telecom Equipment requiring switching the Ethernet port from front to back of the rack, TI specifically set out to design a LAN switch with high bandwidth to assure Gigabit Ethernet speeds. The TS3L301, 8-channel SPDT (2:1 Multiplexer/Demultiplexer) LAN Switch, provides industry-leading bandwidth (900 MHz Typ) for successful implementation in today´s systems.

The TS3L301 is the highest-performance system solution of this type offered by TI. In addition to the high bandwidth, the device offers low input/output capacitance (Con = 6pF Typ), low and flat ON-state resistance (r(on) = 4 ohms Typ, r(on) (flat) = 0.7 ohms Typ), and low differential crosstalk (XTALK = -41 dB Typ). The low and flat On-state resistance prevents large signal variation and degradation across frequencies. This is a key parameter in supporting LAN standard data rates for 10Base-T(10Mbps), 100Base-T(100Mbps), and 1000Base-T(1Gbps). This device also incorporates Ioff protection circuitry to help reduce power consumption.

Packaging, Pricing, and Availability

The TS3L301 is offered in both the 48 pin TSSOP (DGG) and the 48-pin TVSOP (DGV). Both package offerings are Lead (Pb)-free and are backwards compatible to leaded manufacturing processes. The TS3L301 is available to sample in both package options. Budgetary pricing for the device is set at $2.00 in quantities of 1,000.
