PCK2509SA Datasheet (NXP) - 50-150 MHz 1:9 SDRAM clock driver

PCK2509SA, 50-150 MHz 1:9 SDRAM clock driver

The PCK2509SA is a high-performance, low-skew, low-jitter, phase-locked 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.

PCK2509SA Features

* Phase-Locked Loop Clock distribution for PC100/PC133 SDRAM applications

* JEDEC compliant operation

* PLL reamins locked when outputs are disabled. adjusted to 50 percent, independent of the duty cycle at CLK. Each bank of outputs can be enabled or disabled separately via
