ICS307-01/02

Determining the Output Frequency

On power-up, the ICS307-01 on-chip registers can

have random values so almost any frequency may be

output from the part. CLK1 will always have some clock

signal present, but CLK2 could possibly be OFF (low).

The ICS307-02 on-chip registers are initially configured

to provide a x1 output clock on both the CLK1 and

CLK2 outputs. The output frequency will be the same

as the input clock or crystal. This is useful if the ICS307

will provide the initial system clock at power-up. Since

this feature is an advantage in most systems, the

ICS307-02 is recommended for new designs.

With programming, the user has full control in changing

the desired output frequency to any value over the

range shown in Table 1 on page 4. The output of the

ICS307 can be determined by the following equation:

Where:

VCO Divider Word (VDW) = 4 to 511 (0, 1, 2, 3

are not permitted)

Reference Divider Word (RDW) = 1 to 127 (0 is

not permitted)

Output Divider = values on page 4

The following operating ranges should be observed.

For the commercial temperature range:

And for the industrial temperature range:

and output dividers, see the online calculator at
