2.4.2 Implementation Example

Figure 2-4. Main Oscillator Connection
Figure 2-5. 32 kHz Oscillator Connection

In the design schematic below, the SAMA5D2 MPU features the 12MHz DSC1001DL5-012.0000 MEMS oscillator as default main clock source and the NX2012SA-32.768K-STD-MUB-1 crystal loaded with 18 pF capacitors to provide the 32.786 kHz slow clock. Alternatively, by removing R1 and R2 resistors and populating the corresponding parts associated with Y2, then the CX3225SB12000H0PSTC1 12MHz crystal oscillator is used as main clock source.
