PRODUCT
FS786/787
SSCG Modulation Profile
The digital control input D0 determines the modulation frequency of the FS786 and FS787 products. The
modulation frequency is determined by dividing the input frequency by a constant divisor. One of 4 divisor
numbers are used, depending on the device and setting of D0. The modulation frequency of the FS786/787 can
be determined from Table 8. Select the device and input frequency on Table 8 and read the Modulation Divider.
Then, divide the input frequency by the Modulation Divider.

Figure 5. Frequency Profile in Time Domain
With the correct loop filter connected to pin 4, the profile in figure 5 above will provide the best EMI reduction. This
profile can be seen on a Time Domain Analyzer.
