PRELIMINARY INFORMATION
ICS674-01
User Configurable Divider
Using the ICS674-01 with the ICS673-01:
The ICS674-01 may be used with the ICS673-01 to build a frequency synthesizer. The following example
shows a typical application when the reference clock is in the MHz range:
Reference
Clock
Divide A
REFIN
ICS673-01
FBIN
CLK1
CLK2
Output
Clock
ICS674-01
Post
Divide
Divide B
If the reference is in the kHz range, for example 8 kHz, the following configuration may be more
typical:
Reference
Clock
REFIN
ICS673-01
FBIN
CLK1
CLK2
Output
Clock
Divide A
ICS674-01
Post
Divide
Divide B
Note that in both examples Divide B is connected to the output of the ICS673. This is because Divide B
has a higher operating frequency than Divide A.
