2.0GHz Dual Modulus Prescaler
MC12034A MC12034B
The MC12034A 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 MC12034B can be used with CMOS synthesizers requiring negative
edges to trigger internal counters such as Fujitsu’s MB87001.
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.
