SEMICONDUCTOR TECHNICAL DATA
The MC12036 is a 1.1GHz ÷64/65, ÷128/129 dual modulus prescaler
used in phase–locked loop (PLL) applications. Stand–By mode is
featured to reduce current drain to 0.5mA typical when the standby pin
(SB) is switched LOW, disabling the prescaler. On–chip output
termination provides sufficient output current to drive a 12pF (typical) high
impedance load.

÷64/65, ÷128/129
DUAL MODULUS PRESCALER
WITH STAND–BY MODE
The MC12036A 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 MC12036B 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.
