CDCF2509 Datasheet (Texas Instruments) - 3.3-V Phase-Lock Loop Clock Driver

CDCF2509, 3.3-V Phase-Lock Loop Clock Driver

The CDCF2509 is a high-performance, low-skew, low-jitter, phase-lock loop (PLL) clock driver.

It uses a PLL to precisely align, in both frequency and phase, the feedback (FBOUT) output to the clock (CLK) input signal.

It is specifically designed for use with synchronous DRAMs.
