Figure 2-4. Processor Configuration

In the above design schematic, the SAMA7D65 MPU features the 24 MHz ECS-240-10-37B2-JTN-TR crystal oscillator loaded with 18 pF capacitors as the default main clock source and the FC-12M 32.7680KA-A3 crystal loaded with 20 pF capacitors to provide the 32.786 kHz slow clock. Alternatively, by removing the R41 and R42 resistors and populating the corresponding parts associated with Y2, the DSC6001HI1B-024.0000T 24 MHz MEMS oscillator can be used as main clock source.
