GENERAL DESCRIPTION
The ICS84330 is a general purpose, single output high frequency synthesizer and a member of the HiPerClockS™ HiPerClockS™ family of High Performance Clock Solutions from ICS. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO and output frequency can be programmed using the serial or parallel interfaces to the configuration logic. The output can be configured to divide the VCO frequency by 1, 2, 4, and 8. Output frequency steps from 250KHz to 2MHz can be achieved using a 16MHz crystal depending on the output divider setting.
