ICS84329B-01

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.
