ESCRIPTION
The ICS8427-02 is a general purpose, six
LVHSTL output high frequency synthesizer
and a member of the HiPerClockS family of
High Performance Clock Solutions from ICS.
The ICS8427-02 can support a very wide
output frequency range of 15.625MHz to 500MHz. The
device powers up at a default output frequency of
200MHz with a 16.6667MHz crystal interface, and the
frequency can then be changed using the serial programm-
ing interface to change the M feedback divider and N
output divider. Frequency steps as small as 125kHz can
be achieved using a 16.6667MHz crystal and the output
divider set for
÷
16. The low jitter and frequency range of the
ICS8427-02 make it an ideal clock generator for most
clock tree applications.
