ICS962621
is a programmable 48 pin clock chip following Intel CK409 Yellow Cover specification. This clock synthesizer provides a single
chip solution for next generation P4 Intel processors and Intel chipsets.
ICS962621
is driven with a 14.318MHz crystal. It generates CPU
outputs up to 200MHz. It also provides a tight ppm accuracy output for Serial ATA support.
