GENERAL DESCRIPTION

The ICS84314 is a general purpose quad output frequency synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. 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 2 or divide by 4, providing a frequency range of 62.5MHz to 350MHz. The low cyclecycle jitter and broad frequency range of the ICS84314 make it an ideal clock generator for a variety of demanding applications which require high performance.
