Notes

1. The typical value of ICOMP(0) is set by the fractional-N accumulator value Acc and the current Irsc set by the external

resistor RSC, where Ico=Irsc /128. Irsc is typically 12.8µA.

2. The typical value of ICOMP(1) is set by the value of ICOMP(0) and the programmed value of L.

3. The current output ICOMP is specified up to 12µA.

4. The typical value of ICOMP2 is set by the value of ICOMP(1) and the programmed value of K.

5. The current output ICOMP2 is specified up to 180µA.
