700MHZ, LOW JITTER, CRYSTAL-TO-3.3V
DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84329B-01 is a general purpose, single
ICS
output high frequency synthesizer and a member
HiPerClockS™ _{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.
FEATURES
