Consider MC12054A for New Design
2.0GHz 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.
NOTE: The “B” Version Is Not Recommended for New Designs

NOTES: 1. SW: H = VCC, L = Open. A logic L can also be applied by grouunding this pin,
but this is not recommended due to increased power soncumption.
2. MC: H = 2.0 V to VCC, L = GND to 0.8 V.
