Integer multiple of 250kHz
The difference between the internal capacitance at minimum and maximum settings of the internal digital trim.
XTAL frequency = 16MHz; XTAL C0 = 0.75pF; XTAL load capacitance = 8.5pF.
Clock input can be any frequency between 8MHz and 40MHz in steps of 250kHz plus CDMA/3G TCXO frequencies of
7.68, 14.44, 15.36, 16.2, 16.8, 19.2, 19.44, 19.68, 19.8 and 38.4MHz.
Clock input can be either sinusoidal or square wave. If the peaks of the signal are below VSS_ANA or above VDD_ANA.
A DC blocking capacitor is required between the signal and XTAL_IN.
