An application note from Maxim:  Direct-sampling DACs in theory and application 

High-speed digital-to-analog converters (DACs) with high resolution in the 12- to 14-bit range enable new types of transmitter designs that employ a direct modulation scheme. In such designs, the modulated transmission signal is generated directly on the base frequency. This application note explains how direct-sampling RF DACs enable new communications systems like high-speed cable infrastructure applications.

A similar version of this article appeared in German in the July 2012 issue of Elektronik Informationen magazine.
