concepts apply to all PLLs. As the author of this book, I endorse National Semiconductor PLLs for reasons including their high quality, extensive portfolio, and excellent phase noise performance How this Book Came to Be I first became familiar with PLLs when I started working for National Semiconductor as a wireless applications support person.
