Crystal Interface and Clock Generation
b. With a 26 MHz reference clock. For a 13 MHz clock, subtract 6 dB. For a 52 MHz clock, add 6 dB.
c. Auto-detection of the frequency requires the crystal or external frequency reference to have less than ±50 ppm
of variation and also requires an external LPO frequency which has less than ±250 ppm of variation at the time
of detection.
d. AT-Cut crystal or TXCO recommended.
