Zarlink Semiconductor Inc.
Example 1: Calculate the binary value that must be written to the MCFC register to correct a -1ppm offset of the
Master Crystal Oscillator. The -1ppm offset for a 20 MHz frequency is equivalent to -20 Hz:
MCFC = 45036 * 20 = 900720 = 00 0D BE 70 H
Note: Correcting the -1ppm crystal offset requires +1ppm MCFC offset.
Example 2: Calculate the binary value that must be written to the MCFC register to correct a +2 ppm offset of the
Master Crystal Oscillator. The +2 ppm offset for 20 MHz frequency is equivalent to 40 Hz:
MCFC = 45036 * (-40) = -1801440 = FF E4 83 20 H
