PCI Clock Generator
Description
The MK1493-01 is a general purpose clock generator
part that provides an integrated clocking solution for
PCI /networking applications. It provides 8 individually
programmable PCI clocks, 2 CPU clocks, additional
fixed PCI clocks and a 25 MHz reference clock for LAN
support. This part incorporates ICS’s newest clock
technology, offering more robust features and
functionality. Using a serially programmable SMBus
interface, the MK1493-01 can select the output clock
frequency, and enabling/disabling each individual
output clock.
Features
8 PCI clocks at 25, 33, 50, 66.66 MHz individually pin
selectableand serioal port slectable
2 CPU clocks at 100 MHz
2 PCI clocks at 66.66 MHz
1 PCI clock @ 50 MHz
25 MHz reference clock
SMBus Programming
Power-up default frequency can be selected through
