ESCRIPTION
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 fre-
quency 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 config-
ured to divide the VCO frequency by 1, 2, 4, and 8. Output fre-
quency steps from 250KHz to 2MHz can be achieved using a
16MHz crystal depending on the output divider setting.
