HD74CDCV857 - 2.5-V Phase-lock Loop Clock Driver

Description

The HD74CDCV857 is a high-performance, low-skew, low-jitter, phase locked loop clock driver.

It is specifically designed for use with DDR (Double Data Rate) synchronous DRAMs.

Features

  • Supports 60 MHz to 200 MHz operation range.
  • Distributes one differential clock input pair to ten differential clock outputs pairs.
  • Supports spread spectrum clock requirements meeting the PC100 SDRAM registered DIMM specification.
  • External feedback pins (FBIN, FBIN) are used to synchronize the outputs to the clock input.
  • Supports 2.5V analog supply voltage (AVCC), and 2.5 V VDDQ.
  • No external RC network required.
  • Sleep mode detection.
