Development of a CMOS Data Recovery PLL for DVD-ROMx14

摘要

In this paper, a CMOS data recovery PLL for DVD- ROM is described. Some techniques have been introduced to alleviate The specifications required to analog circuits. A new phase detector al- Leviates the timing specification of a delay line and a pulse generator. A New frequency detector increases the capture range up to 8/100 of the Center frequency. We have achieved to realize the data recovery PLL That operates at DVD-ROMx14 speed.
