This talk will discuss the fundamentals of digital phase-locked loops and analyze the mechanisms of generation of limit cycles, which manifest themselves as spurious tones at the output. Then, we will compare two different quantization strategies and develop practical design examples showing how to set loop parameters and optimize phase noise and jitter. The second part of the tutorial will be devoted to fractional-N synthesis, in which quantization and nonlinearity add new sources of spurious tones: We will review the different design techniques which help mitigate such impairments.
