ICS8431-11
CLOCK SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS8431-11 is a general purpose clock
frequency synthesizer and a member of the
HiPerClockS
family of High Performance
Clock Solutions from ICS. The VCO operates at
a frequency range of 280MHz to 400MHz. The
output frequency can be programmed using the parallel inter-
face, M0 thru M8, to the configuration logic. Spread spectrum
clocking is programmed via the Power Up Latch inputs
SSC_CTL0 and SSC_CTL1.
