TI Introduces High-Port-Density Gigabit Ethernet Transceiver

Mar 30, 2006

DALLAS (March 30, 2006) - Texas Instruments (TI) [NYSE: TXN] introduced today a six-channel Gigabit Ethernet transceiver that provides a full-featured, flexible interface in data communications and telecommunications equipment. The device combines high port-density with a small footprint and ultra-low power operation of less than 1.5 W at 1.25 gigabits per second (Gbps) to reduce overall system cost, board space and power consumption. (See www.ti.com/sc06071.)

The TLK2226 provides for high-speed, full-duplex, point-to-point data transmission based on the IEEE 802.3z 1000-Mbps Ethernet specification, and it is compatible with the IEEE 100Base-FX Ethernet specification. The device increases designers' flexibility, allowing them either to set each channel's data rate through management data input/output (MDIO) or to have it automatically sensed and set by the TLK2226.
The TLK2226 performs the data encoding, decoding, serialization, deserialization, clock extraction and clock tolerance compensation functions for a physical layer interface device. Each of the device's six synchronizable transceivers operates at up to 1.3 Gbps, providing up to 7.5 Gbps of aggregate data bandwidth over a copper or optical media interface. The TLK2226 supports RGMII, RTBI and SGMII reduced pin-count interfaces, which simplifies designs.
The TLK2226 complements other recent products introduced by TI for data communications and telecommunications applications such as the CDCLVP110 1-to-10 LVPECL clock distribution device and the SN65LVCP40 dual MUX buffer with equalization for redundant switching of signals up to 4 Gbps.

Availability and Pricing

The TLK2226 is available today in volume in a small footprint 15 mm x 15 mm, 196-pin, 1-mm ball-pitch ball grid array (BGA) package from TI and its authorized distributors. Suggested resale pricing in quantities of 1,000 is $19.65 each.
