PCK2509S - 50-150 MHz 1:9 SDRAM clock driver

General 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.

Key Features

  • Phase-Locked Loop Clock distribution for PC100/PC133 SDRAM.
