ICS8431-01
CLOCK SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS8431-01 is a general purpose clock
frequency synthesizer and a member of the
HiPerClockS family of High Performance
Clock Solutions from ICS. The ICS8431-01
consists of one independent low bandwidth PLL
timing channel. A 16.666MHz crystal is used as the input to
the on-chip oscillator. The M and N dividers are configured to
produce a fixed output frequency of 200MHz.
Programmable features of the ICS8431-01 support four op-
erational modes. The four modes are spread spectrum clock-
ing (SSC), non-spread spectrum clock and two test modes
and are controlled by the Power Up Latch. After power up
the latch is disabled and the initial programmed values can
only be overwritten by removing all power to the device.
In SSC mode the output clock is modulated in order to achieve
a reduction in EMI. In one of the PLL bypass test modes the
PLL is disconnected as the source to the differential output
allowing an external source to be connnected to the
TEST_I/O pin. This is useful for in-circuit testing and allows
the differential output to be driven at a lower frequency
throughout the system clock tree. In the other PLL bypass
mode the oscillator divider is used as the source to both the
M and N dividers. In this configuration the frequency at FOUT,
nFOUT equals the crystal frequency divide by 16 divided by
N. The frequency at TEST I/O equals the crystal frequency
divide by 16 divided by M. This is useful for characterizing
the oscillator and internal dividers.
