CKO/PLLO Output Frequency Range
The M66238 requires an internal VCO oscillator frequency of 25 MHz to 50 MHz.
Settings of dividing ratio K of 12-bit divider and dividing ratio N of 15-bit counter are required in order to determine
the internal VCO oscillator frequency. The relation between the settings and the internal VCO oscillator frequency is
shown below.

K =

26
n = 12
N =
Σ (Dn × 2n12)
Note: 3. Setting of fin / K
≥ 100 kHz is recommended in consideration of the frequency accuracy characteristics of
PLL output.
Therefore, set the division ratio K of the 12-bit divider and the division ratio N of the 15-bit counter to meet
the following conditions:
25 MHz
≤ fvco ≤ 50 MHz
In addition, for PLLO and CKO, setting the division ratios of the sync/division circuit (synchronous clock
generating area) to 1/1, 1/2, 1/4, 1/8, 1/16, 1/32 will allow the frequencies of 0.78 Hz to 50 MHz to be
accommodated.
