Fig.20 Real time control output.
(1) Set to zero for one transmission, if a phase reset of the fsc DTO is applied via I2C-bus bit CDTO. RTCO sequence is generated in LLC/4.
The HPLL increment represents the actual LFCO frequency (fLFCO × 4=fLLC); 16 LSB from 20, upper four bits are fixed to 0100b.
Where: fXTAL = 24.576 MHz, word length DTO2 = 20 bits.
The fsc increment represents the actual subcarrier frequency (related to the actual clock); 23 LSB from 24, MSB is 0b.
Where: word length DTO1 = 24 bits.
