External Crystal
A 12 MHz ± 50 PPM fundamental frequency external crystal must be connected between the XTALIN and XTALOUT pins
of the XR22404 device. The crystal should have a rated load capacitance of 16-20pF. However, note that both the load
capacitors and feedback resistance are internal to the XR22404 device as shown.
