High-speed ADC SNR beyond the state of the art

Posted: 10 Sep 2008     Print Version  Bookmark and Share

Keywords:ADC  dynamic range  converters 

The wireless communications field is constantly demanding faster and higher resolution high-speed data converters to enable them to process more bandwidth (allowing more channels) with greater resolution. One way to further advance state-of-the-art analogue-to-digital converters (ADC) is to average multiple high-speed ADCs to increase the dynamic range.

This article shows the actual results of combining three TI ADS5546 converters (14-bit, 190 Msps), using the second option of paralleling the ADCs. It addresses the clock jitter requirement which engineers face with the implementation.
