12.6 PLL N DIVIDER CONFIGURATION REGISTER
This register is used to control the feedback divider of the PLL.
TABLE 7. PLL_N (0x03h)
Bits
7:0
Field
PLL_N
Description
Programs the PLL feedback divider as follows:
PLL_N
0 to 10
11
12
13
14
…
249
250 to 255
Feedback Divider Value
10
11
12
13
14
…
249
250
The N divider should be set such that the output of the divider is between 0.5 MHz and 5 MHz. (Fin/M)*N will be the target resting
VCO frequency, F
. The N divider should be set such that 40 MHz
<
(Fin/M)*N
<
60 MHz. Fin/M is often referred to as F
comp
(comparison frequency) or F
ref
(reference frequency), in this document F
comp
is used.
The integer division of the N divider is derived from PLL_N such that:
For 9
<
PLL_N
<
251: N = PLL_N
