The MC12026 is a high frequency, low voltage dual modulus prescaler
used in phase–locked loop (PLL) applications.
The MC12026A 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 1.1GHz in programmable
frequency steps.
The MC12026B can be used with CMOS synthesizers requiring
negative edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of an 8/9 or 16/17 divide
ratio as desired.
The Modulus Control (MC) selects the proper divide number after SW
has been biased to select the desired divide ratio.
