Cm is chosen according to following relation: Cm = 2(Cl – Cp) – 10pF, where Cl = Crystal load capacitance and Cp = parasitic capacitance NOTE1. All functional options have been implemented in this application. If all options are not used, following components can be deleted: ~Rd, Ru, Cd and Cu: if no mixed-decay mode id selected. ~Rh and Ch: if holding torque is not selected. In this case Vrefh pin is tied to GND. |
