PRINCIPLES OF OPERATION
digital integrator gain selections
In Table 4, EEPROM bits can be set for different clocking rates of the digital integrator. In effect, this allows for
different integrator gain, thereby allowing the user to optimize loop performance (see Figure 12). The integrator
circuit actually utilizes 14 bits with a 4-bit pre-integrator prior to the 10 bits which are output to the digital filter.
This design increases resolution in the error detected by the speed discriminator while reducing the bit-count
output to the digital filter.
