First all-in-one transceiver for 10-Gbps Ethernet standards

Texas Instruments (TI) has unveiled the industry’s first quad-channel XAUI/10GBASE-KR transceiver that can support multiple 10G/40G Ethernet standards, as well as proprietary data rates from 1 Gbps to 10 Gbps. The flexible TLK10034 physical layer (PHY) serializer/deserializer (SerDes) allows engineers to use one SerDes for all of their protocol needs, instead of stocking multiple devices.

The TLK10034 interfaces to backplanes, copper cables, and SFP+ optical modules in server, storage and enterprise networking equipment.

Key features of the device include: multiple protocol flexibility, with each of the four bi-directional channels supporting 10GBASE-KR, XAUI, 1GBASE-KX, CPRI, and OBSAI standard protocols, providing engineers with the maximum flexibility ithey need n their system designs. Optimised link performance, with link training seamlessly bringing up the link, helps to optimise the transmitter pre-emphasis levels to minimise system bit error rate (BER).

The device consumes 825 mW (typical) per channel, compared to competitive SerDes that consume more than 1 W.

A GUI software tool for the TLK10034EVM can be downloaded to manage device provisioning and testing, and HSPICE and IBIS-AMI models are available to verify the TLK10034’s signal integrity.
