APPLICATIONS INFORMATION
Programming the MPC93R52
The MPC93R52 supports output clock frequencies from
16.67 to 240 MHz. Different feedback and output divider
configurations can be used to achieve the desired input to
output frequency relationship. The feedback frequency and
divider should be used to situate the VCO in the frequency
lock range between 200 and 480 MHz for stable and optimal
operation. The FSELA, FSELB, FSELC pins select the
desired output clock frequencies. Possible frequency ratios
of the reference clock input to the outputs are 1:1, 1:2, 1:3,
3:2 as well as 2:3, 3:1, and 2:1. Table 7 and Table 8 illustrate
the various output configurations and frequency ratios
supported by the MPC93R52. See also Figure 3 to Figure 6
for further reference. A ÷2 output divider cannot be used for
feedback.
