Description

The HD74CDCF2510B is a high-performance, low-skew, low-jitter, phase-lock loop clock driver. It uses a phase-lock loop (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. The HD74CDCF2510B operates at 3.3 V VCC and is designed to drive up to five clock loads per output.
