描述

The 84314-02 is a general purpose quad output frequency synthesizer. When the device uses parallel loading, the M bits are programmable and the output divider is hard-wired for divide by 2 thus providing a frequency range of 125MHz to 350MHz. In serial programming mode, the M bits are programmable and the output divider can be set for either divide by 1, 2, 4 or divide by 8, providing a frequency range of 31.25MHz to 700MHz. Additionally, the device supports spread spectrum clocking (SSC) for minimizing Electromagnetic Interference (EMI). The low cycle-cycle jitter and broad frequency range of the 84314-02 make it an ideal clock generator for a variety of demanding applications which require high performance.
