ESCRIPTION
The ICS84329 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 fre-
quency 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 as
small as 125KHz to 1MHz can be achieved using a 16MHz
crystal depending on the output dividers.
