TI unveils all-in-one transceiver for 10-Gbps Ethernet standards

Texas Instruments Inc. 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.

Key highlights:

• Multiple protocol flexibility: Each of the four bi-directional channels supports 10GBASE-KR, XAUI, 1GBASE-KX, CPRI, and OBSAI standard protocols, providing engineers with maximum flexibility in their system designs.
• Optimized link performance: Link training seamlessly brings up the link, and optimizes the transmitter pre-emphasis levels to minimize system bit error rate (BER).
• Reduced power consumption: Consumes 825 mW (typical) per channel, compared to competitive SerDes that consume more than 1 W.
• Higher signal integrity: 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. 

Availability, packaging and pricing

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