Spread Spectrum Programming
b(14:8)
These Spread Spectrum bits
in Byte 13 and 14 will program
the spread pecentage. It is
recommended to use ICS
Spread % table for spread
programming.
The decimal representation of
M and N Divier in Byte 17 and
18 will configure the VCO
frequency. Default at power
up = Byte 0 Rom table. VCO
Frequency = 14.318 x
[NDiv(9:0)+8] / [MDiv(5:0)+2]
M Divider Programming bits
N Divider Programming b(7:0)
These Spread Spectrum bits
in Byte 13 and 14 will program
