Preliminary Product Preview
Low Cost 16-Pin Frequency Generator
The
ICS9154A-39
is a 0.8mm technology low-cost frequency
generator designed for general purpose PC and disk drive
applications. However, because the
ICS9154A-39
uses 0.8mm
technology and the latest phase-locked loop architecture, it
offers significant performance advantages that enable the
device to be used in high performance systems when clock
jitter is a key design issue.
The
ICS9154A-39
guarantees a 45/55 duty cycle over all
frequencies. In addition, a worst case jitter of ±250ps is
achieved.
The CPU clock offers the unique feature of smooth, glitch-
free transitions from one frequency to the next, making this
the ideal device to use whenever slowing the cpu speed. The
ICS9154A-39
makes a gradual transition between
frequencies.
