Texas Instruments’ new TLK3118 serializer/deserializer (SERDES) is a redundant XAUI serial transceiver that is compliant with the IEEE 802.3ae specification for 10 Gbit/sec Ethernet.

Texas Instruments’ new TLK3118 serializer/deserializer (SERDES) is a redundant XAUI serial transceiver that is compliant with the IEEE 802.3ae specification for 10 Gbit/sec Ethernet, providing bi-directional, point-to-point data transmission for backplane and front plane connections.

Within backplane designs, the TLK3118 enables higher port density systems by reducing board space, system costs and power consumption. It performs the parallel-to-serial conversion, serial-to-parallel conversion and clock extraction functions for a physical layer interface. It also provides a complete XGXS (10 Gigabit extended sublayer) function with a redundant serial (XAUI) port.

The device employs both transmit and receive equalisation to retain signal integrity over industry standard media such as FR4 backplanes, enabling TI to achieve error-free data transmission over 80 inches of backplane. It has a low power dissipation of 1.6W (with HSTL termination turned off) at 3.125 Gbit/sec.

Sampling now to partner customers, production is planned for 3Q04. The device is packaged in a 21x21mm, 400-ball, 1mm ball pitch Ball Grid Array (FC-BGA) package. Planned pricing in quantities of 1,000 is $60 per unit.
