3.2.3.1 Main Clock Circuitry

The main clock oscillator is implemented with a MEMS (Micro Electro-Mechanical System) device DSC1001.

For evaluation purposes, the user can mount a crystal instead of the MEMS, using the PCB footprint reservation (Y3). In that case, remove resistors R34 and R36, populate resistors R37 and R40 and populate capacitors C76 and C81 with the appropriate load capacitance for the selected crystal.
