1 GHz Dual Modulus Prescaler The MC12028A 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.
1 GHz in programmable frequency steps.
The MC12028B can be used with CMOS synthesizers requiring negative edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of a 32/33 or 64/65 divide ratio as desired.
The Modulus Control (MC) selects the proper divide number after SW has been biased to select the desired divide ratio.
NOTE: The “B” Version Is Not Recommended for New Designs MC12028B MECL PLL COMPONENTS ÷64/6...
