Clock and Data Recovery

This is a reference textbook for readers that desire to complete and to render systematic their knowledge on this subject.

This book provides the electronic engineer with the knowledge of:

- what the CDR function and structure are

- where a CDR is used in a communication network

- the mathematical models (just three!) needed to understand the CDR operation (no matter how complex its actual implementation is!).

Prior knowledge of calculus and some experience with Fourier and Laplace transforms are required.

• Introduction
  • Definition of (phase) jitter
  • Jitter is far from sinusoidal..
  • Models can only be linear..
  • Acquisition, tracking and jitter performances
• Buffer Memory (Elastic Buffer)
  • Clock domains
  • Cascades of Buffers and CDRs, delays and tolerance
  • Burst and Continuous transmission modes
• Structures and types of CDRs
  • • The CDR' amplifier/filter
    • The CDR phase comparator
    • The CDR Phase and Frequency Detector PFD
    • The CDR' VCO
  • Examples
  • The jitter tolerance function
  • The noise spectrum is shaped by the PLL structure
  • 1st order (type 1) loop
    • Applications of the 1st order type 1 architecture
  • 2nd order type 1 and 2 (slave) loops
    • 2nd order type 1
      • Applications of the 2nd order type 1 architecture
    • 2nd order type 2
      • Applications of the 2nd order type 2 architecture
• Miscellanea
• Conclusion
