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.
