KM1102 is the 16 interpolation LSI which outputs digital 64 edges from 2-phase analog input signals. This LSI inputs sine and cosine signals from an analog encoder and divides the voltage by inserting the unique size of polio-silicon resistors between 2-nodes and compensated the amplitude and comparing to the reference. Then output feeds into the logic circuit to create the digital output, proportioning with the input phase change. This LSI enables the optical, magnetic or Laser type encoder more precious and value added with simple and low cost.
