All-in-one transceiver supports 10-Gbps Ethernet standards

October 18, 2012 // By Paul Buckley
Texas Instruments Incorporated has introduced the industry’s first quad-channel XAUI/10GBASE-KR transceiver that supports 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.

Each of the TLK10034’s four bi-directional channels supports 10GBASE-KR, XAUI, 1GBASE-KX, CPRI, and OBSAI standard protocols, providing engineers with maximum flexibility in their system designs.

Link training seamlessly brings up the link, and optimizes the transmitter pre-emphasis levels to minimize system bit error rate (BER).

The flexible TLK10034 consumes 825 mW (typical) per channel, compared to competitive SerDes that consume more than 1 W.

Forward error correction (FEC) manages the signal integrity performance by compensating up to 29-dB insertion loss at 6 GHz to improve BER and system margin.

System designers can create a robust data link by combining the TLK10034 with the LMK04906 clock jitter cleaner/multiplier.

Availability and Pricing

The TLK10034 is available today in a 19-mm by 19-mm, 324-pin PBGA package for a suggested retail price of $45 in 1,000-unit quantities.

The TLK10034EVM evaluation module (EVM) can be purchased today for $2999, and the TLK10034SMAEVM SMA breakout daughterboard can be purchased for $1499 to evaluate low-speed signals. 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.
