1 / 19 page  84329BM-01 www.icst.com/products/hiperclocks.html REV. A JUNE 10, 2005 1 Integrated Circuit Systems, Inc. ICS84329B-01 700MHZ, LOW JITTER, CRYSTAL-TO-3.3V DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER GENERAL DESCRIPTION The ICS84329B-01 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 250MHz 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 as small as 125kHz to 1MHz can be achieved using a 16MHz crystal depending on the output dividers.
