Unveiling its first LAN switch that supports Gigabit Ethernet LAN switching, Texas Instruments set out to design a LAN switch with high bandwidth to assure Gigabit Ethernet speeds.

Texas Instruments Incorporated has unveiled 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 (ron = 4 Typ, ron (flat) = 0.7 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(10Mb/s), 100Base-T(100Mb/s), and 1000Base-T(1Gb/s).

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.
