Overview
The W42C32 modulates the output of a single PLL in order to ‘spread’ the bandwidth of a synthesized clock and, more importantly, decrease the peak amplitudes of its fundamental harmonics. Since peak amplitudes are reduced, the radiated electromagnetic emissions of the W42C32-05 are significantly lower than the typical narrow band signal produced by oscillators and most frequency generators.
