Everyone Needs to Understand High Speed Digital Design Techniques

As the digital portion of electronic equipment gets closer to the antenna, there is a corresponding need for traditional “RF engineers” to understand digital design techniques. Whether or not they are involved in the design of the actual digital circuitry is unimportant—whatever part they are working on will eventually interface with the digital part. Analog and digital performance are interdependent. Linearity of analog circuits affects the accuracy of the data being transmitted. Bit rate, symmetry of the bitstream and the specific coding of the digital signal can affect the performance of analog circuits, and certainly establishes their required performance.
