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 alleviates the timing specification of a delay line and a pulse generator. A new frequency detector increases the capture range up to 8% of the center frequency. We have achieved to realize the data recovery PLL that operates at DVD-ROMx14 speed.
