APPLICATIONS INFORMATION
Programming the MPC9600
The MPC9600 clock driver outputs can be configured into
several divider modes. Additionally the external feedback of the
device allows for flexibility in establishing various input to output
frequency relationships. The selectable feedback divider of the
three output groups allows the user to configure the device for 1:2,
1:3, 1:4 and 1:6 input:output frequency ratios. The use of even
dividers ensure that the output duty cycle is always 50%. Table 8
illustrates the various output configurations, the table describes
the outputs using the input clock frequency CLK as a reference.
The feedback divider division settings establish the output
relationship, in addition, it must be ensured that the VCO will be
stable given the frequency of the outputs desired. The feedback
frequency should be used to situate the VCO into a frequency
range in which the PLL will be stable. The design of the PLL
supports output frequencies from 50 MHz to 200 MHz while the
VCO frequency range is specified from 200 MHz to 400 MHz and
should not be exceeded for stable operation.
