HD74CDCF2509B Datasheet 140 Mhz/ 0 To 85c Operation 3.3-v Phase-lock Loop Clock Driver

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74CDCF2509B 140 MHz, 0 to 85°C Operation 3.3-V Phase-lock Loop Clock Driver ADE-205-224F (Z) 7th.

General Description

The HD74CDCF2509B 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.

Key Features

  • Supports PC133 and meets “PC SDRAM registered DIMM specification, Rev. 1.1” Phase-lock loop clock distribution for synchronous DRAM.
