ADVANCE INFORMATION
Integrated
Circuit
Systems, Inc.
ICS8432-21
700/87.5MHZ, LOW PHASE NOISE
LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS8432-21 is a general purpose, dual out-
put high frequency synthesizer and a member of
the HiPerClockS family of High Performance
Clocks Solutions from ICS. The VCO operates at
a frequency range of 250MHz to 700MHz. Out-
put frequencies up to 700MHz for FOUT and 175MHz for
FOUT/P can be programmed using the serial or parallel inter-
faces to the confiquration logic. The low phase noise and dual
output frequency range of the ICS8432-21 makes it an ideal
clock generator for Infiniband applications.
