VR1: Charge pump reference voltage 5.6 (V: See the electrical characteristics table.) 2. The voltage gain (Gfg) of the FG amplifier is determined by the following formula. Here Rfgf is the internal feedback resistance. See the electrical characteristics table. However, note that R103 must be equal to R104. Gfg = Rfgf R103
3. The output current limit is given by the following formula. Iomax = (VX1 -- 25 mV) Rnf (A)
4. The PWM carrier frequency is determined by the following formula. Here VR1 and K are the charge pump voltage and the oscillator amplitude (see the electrical characteristics table), respectively. . VR1 fP = (Hz) . KCt R1 VOSC 5. The FG amplifier bandwidth BW is determined by the following formula. Here Rfgo is the pin 15 output resistance. See the electrical characteristics table. However, when C105 is 0, BW is limited to 8 kHz by the internal capacitance. BW = 1 2 C105 Rfgo (Hz)
6. Determine C106 using the following formula as a rough estimate. C106 1 (R103 + R104) fFG (F)
Consult with the oscillator element manufacturer. 7. Relationship of between the CLK frequency fc and the FG frequency fFG. Are determined by the under table. D 1/3 1/6 1/12 2048.5 * 2048.5 * fc (Hz) fFG D fFG D But rotation response is 80 ppm down
8. If an input of 1.25/GFG (Vp-p) or higher is applied, irregular rotation may occur due to FG amplifier saturation. 9. The absolute value of the whole amplifier input voltage must be within the in-phase input voltage range. 10. This should be decided after consultation with the oscillator manufacturer. 11. Determine C109 using the following formula as a rough estimate. 3 k R107 6 k 300pF < C109 20 Fc (R108 + 200 ) (F)

12. TAB should be connected to pin 23 (GND). The FG amplifier may not operate normally, causing irregular rotation, due to parasitism during phase switching.
