Description

The ICS84329 is a general purpose, single output high frequency synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The VCO operates at a frequency range of 200MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the crystal frequency divided by 16. 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 of the ICS84329 as small as 125KHz to 1MHz can be achieved using a 16MHz crystal depending on the output dividers.
