Notes:
1. For sine–wave input signal. Prescaler will operate down to dc for square–wave input signal. Min. divide frequency limited by input slew rate.
2. Prescaler can exhibit this output signal under bias in the absence of an RF input signal. This condition can be eliminated by use of the Input dc offset
technique described on page 4.
3. Fundamental of output square wave’s Fourier Series.
