0GHz Dual Modulus Prescaler MC12032A MC12032B The MC12032A can be used with CMOS synthesizers requiring positive edges to trigger internal counters such as Motorola’s MC145XXX series in a PLL to provide tuning signals up to 2.
0 GHz in programmable frequency steps.
The MC12032B can be used with CMOS synthesizers requiring negative edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of a 64/65 or 128/129 divide ratio as desired.
The Modulus Control (MC) selects the proper divide number after SW has been biased to select the desired divide ratio.
