MC12439 generator equivalent, high frequency pll clock generator.
ve M in the appropriate direction. The M and N counters can be loaded either through a parallel or serial interface. The parallel interface is controlled via the P_LOAD s.
that require both serial and parallel interfaces. Its internal VCO will operate over a range of frequencies from 400 to .
The internal oscillator uses the external quartz crystal as the basis of its frequency reference. The output of the reference oscillator is sent directly to the phase detector. With a 16.66MHz crystal, this provides a reference frequency of 16.66MHz..
