Note1: For best performance and accurate frequencies from this device, It is recommended but not mandatory that the
chosen crystal meets or exceeds these specifications
Note 2: Larger values may cause this device to exibit oscillator startup problems
To obtain the maximum accuracy, the total circuit loading capacitance should be equal to CXTAL. This loading
capacitance is the effective capacitance across the crystal pins and includes the clock generating device pin
capacitance (CFTG), any circuit traces (CPCB), and any onboard discrete load capacitors (CDISC).
