Frequency Generator with 133MHz Differential CPU Clocks
TM
All 3V66 clocks are to be in phase with each other. All 66MHz_OUT clocks are to be in phase with each other. There is NO
phase relationship between the 3V66 clocks and the 66MHz_OUT and PCI clocks. In the case where 3V66_1 is configured
as 48MHz VCH clock, there is no defined phase relationship between 3V66_1/VCH and other 3V66 clocks. The PCI group
should lag 3V66 by the standard skew described below as Tpci.
The 66MHz_IN to 66MHz_OUT delay is shown in the figure below and is specified to be within a min and max propagation
value.
