ICS674-01
USER CONFIGURABLE DIVIDER
CLOCK 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
ICS674-01
REFIN
CLK1
ICS673-01
FBIN
CLK2
Post
Divide
Divide B
Ouput Clock
If the reference is in the kHz range, for example 8 kHz, the following configuration may be more typical:
Reference Clock
Divide A
ICS674-01
REFIN
CLK1
ICS673-01
FBIN
CLK2
Post
Divide
Divide B
Ouput Clock
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.
