6.9.4.1.1.1 Load Capacitance
The crystal circuit must be designed such that it applies the appropriate capacitive load to the crystal, as defined
by the crystal manufacturer. The capacitive load, CL, of this circuit is a combination of discrete capacitors
CL1, CL2, and several parasitic contributions. PCB signal traces which connect crystal circuit components to
MCU_OSC0_XI and MCU_OSC0_XO have parasitic capacitance to ground, CPCBXI and CPCBXO, where the
PCB designer should be able to extract parasitic capacitance for each signal trace. The MCU_OSC0 circuits
and device package have combined parasitic capacitance to ground, CPCBXI and CPCBXO, where these parasitic
capacitance values are defined in Table 6-22.

Figure 6-18. Load Capacitance
Load capacitors, CL1 and CL2 in Figure 6-16, should be chosen such that the below equation is satisfied. CL in
the equation is the load specified by the crystal manufacturer.
CL = [(CL1 + CPCBXI + CXI) × (CL2 + CPCBXO + CXO)] / [(CL1 + CPCBXI + CXI) + (CL2 + CPCBXO + CXO)]
