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.
