The ICS950813 is a single chip clock solution for desktop designs using the
Brookdale/Odem/Montara-GM for P4/Banias processor.
The ICS950813 is part of a whole new line of ICS clock generators and buffers called TCH
TM
( Timing Control Hub ). This part incorporates ICS
’
s newest clock technology with offers more
robust features and functionality. Employing the use of a serially programmable I
2
C interface, this
device can adjust the output clocks by configuring the frequency setting, the output divider rations,
selecting the ideal spread percentage, the output skew, the output strength, the enabling / disabling
each individual output clock. M/N control can configure output frequency with resolution up to 0.1
MHz increment.
Output Features
3 Differential CPU Clock Pairs @ 3.3V
7 PCI (3.3V) @ 33.3MHz including 2 early PCI clocks
3 PCI_F (3.3V) @ 33.3MHz
1 USB (3.3V) @ 48MHz, 1 DOT (3.3V) @ 48MHz
1 REF (3.3V) @ 14.318MHz
5 3V66 (3.3V) @ 66.6MHz
