Programming the MPC9230
Programming the MPC9230 amounts to properly configuring
the internal PLL dividers to produce the desired synthesized
frequency at the output. The output frequency can be
represented by this formula:
F
OUT
= (f
XTAL
÷
16)
(4
M)
÷
(2
N) or
F
OUT
= (f
XTAL
÷
8)
M
÷
N
where f
XTAL
is the crystal frequency, M is the PLL feedback-
divider and N is the PLL post-divider. The input frequency and
the selection of the feedback divider M is limited by the
VCO-frequency range. f
XTAL
and M must be configured to
(1)
(2)
match the VCO frequency range of 800 to 1600 MHz in order to
achieve stable PLL operation:
M
MIN
= 4
f
VCO,MIN
÷
f
XTAL
and
M
MAX
= 4
f
VCO,MAX
÷
f
XTAL
For instance, the use of a 16 MHz input frequency requires
the configuration of the PLL feedback divider between M=200
and M = 400.
Table 10
shows the usable VCO frequency and
M divider range for other example input frequencies.
Assuming
that a 16 MHz input frequency is used, equation (2) reduces to:
F
OUT
= 2
M
÷
N
