Keywords:Ethernet  PHY  SerDes  transceiver 

Texas Instruments Inc. launches the TLK10034 PHY SerDes quad-channel XAUI/10GBASE-KR transceiver that supports multiple 10G/40G Ethernet standards and proprietary data rates from 1Gbps to 10Gbps.

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

It offers multiple protocol flexibility because each of the four bi-directional channels supports 10GBASE-KR, XAUI, 1GBASE-KX, CPRI, and OBSAI standard protocols. It features link training that seamlessly brings up the link, and optimises the transmitter pre-emphasis levels to minimise system bit error rate (BER). The device consumes 825mW (typical) per channel, compared to competitive SerDes that consume more than 1W. Alsoforward error correction manages the signal integrity performance by compensating up to 29dB insertion loss at 6GHz to improve BER and system margin.

The TLK10034EVM evaluation module 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.

The TLK10034 is available in a 19mm x 19mm, 324-pin PBGA package at about $45 in 1,000-unit quantities.
