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, glitchfree 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.
