PLL Divisor Setup Example
The reference divider divisor is calculated as follows when a 12.8 MHz crystal element is used, the comparison
frequency in the phase detector is 5 kHz, and the VCO oscillator frequency is 26.545 MHz.
12.8 MHz
÷
5 kHz = 2560 (divisor value)
Since there is a fixed divide-by-two circuit, the required divisor is as follows.
2560
×
1/2 = 1280
The value 1280 converted to binary (10100000000) is the reference divider setting data.
The programmable divider divisor is calculated as follows.
26.545 MHz
÷
5 kHz = 5309 (divisor value)
The value 5309 converted to binary (1010010111101) is the programmable divider setting data.
The control data is set as follows
