DESCRIPTION

The PCK2509S is a high-performance, low-skew, low-jitter, phase-locked loop (PLL) clock driver. It uses a PLLto 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 PCK2509S operates at 3.3 V VCC and is input compatible with both 2.5 V and 3.3 V input voltage ranges. It also provides integrated series-damping resistors that make it ideal for driving point-to-point loads.
