This handbook seeks to provide an in-depth and practical understanding of the digital clock technologies used in building today's telecommunications networks. Covering critical details on the PLL (phase-locked loop) technique for clock synchronization and generation, and the DDS (direct digital synthesizer) technique for clock generation, the work is designed to help the reader achieve synchronization in high-speed networks and frequency stabilization in portable equipment. Discussing both wired and wireless networks, the volume looks at the combination of circuits and systems to give you a more thorough understanding of important design requirements.
