CDC2509B 3.3-V Phase-Lock-Loop Clock Driver

The CDC2509B is a high-performance, low-skew, low-jitter, phase-lock loop (PLL) clock drivers. They use a PLL to precisely align, in both frequency and phase, the feedback (FBOUT) output to the clock (CLK) input signal. They are specifically designed for use with synchronous DRAMs. The CDC2509B ope.
