11/17/2004 - Expanding its leading portfolio of data offerings, Texas Instruments Incorporated (TI) (NYSE:TXN) introduced the highest performing dual 200-MSPS digital-to-analog converters (DACs). The superior design of the DAC5662/72 devices helps to eliminate cross-channel interference, reduces noise and minimizes signal distortion in intensive signal processing applications such as wireless infrastructure, communications, video-imaging, and multimedia.
The unmatched performance of the 200-MSPS DACs allows for increased system capabilities, delivering an SNR of 77dBc and increased SFDR of 84dBc at 5MHz and 100MSPS, which reduces filtering thus saving system components and board space. Also, with their low power dissipation of 311 mW at 100MSPS, the DACs reduce operating costs, improve system reliability while boosting higher channel density in 3G base stations.
Their mode of operation is flexible, each can be used as a standard dual DAC as well as in an interleaved data mode. Additionally, the DAC5662/72 can accept multiplexed data in the interleave mode and features tight gain and offset matching for minimizing IQ imbalance in baseband sampling applications. These new additions to TI's family of digital to analog converter family of products are also pin compatible with the DAC290x series.
"These DACs offer combined high sample-speed, performance and low power which are critical issues for 3G base stations manufacturers," said Mike Walker, product manager for high speed digital and analog converters within TI's analog high speed communications group. "We are pleased to extend TI's technology leadership in the high-performance digital-to-analog converter industry."
TI delivers a complete signal chain solution for wireless infrastructure OEMs. TI's end-to-end approach, developed over 20 years, allows customers to better use development time and dollars on creating differentiated products and services. Complementing the analog portion of the signal chain with the DAC5662/72 and other high performance analog parts, TI offers a broad portfolio of high speed, high performance analog products.
TI also provides developers using the device access to applicable evaluation modules for easy integration of the DAC5662/72 into basestations as well as other target applications.
The DAC5662 and DAC5672 are now available. For more information on this product and TI´s complete portfolio of wireless infrastructure solutions, visit www.ti.com.
