SEMICONDUCTOR TECHNICAL DATA
Legacy Device: Motorola MC12015, MC12016, MC12017
The ML12015, ML12016 and ML12017 are dual modu-
lus prescalers which will drive divide by 32 and 33, 40
and 41, and 64 and 65, respectively. An internal regulator
is provided to allow these devices to be used over a wide
range of power–supply voltages. The devices may be oper-
ated by applying a supply voltage of 5.0 Vdc 10ꢀ at ꢁin
7, or by applying an unregulated voltage source from 5.5
Vdc to 9.5 Vdc to ꢁin 8.

NOTES: 1. Pin 2 connected to Pin 3.
2. t
= the period of time the PLL has from the prescaler rising output tranistion (50%) to the modulus control input edge transition
PLL
(50%) to ensure proper modulus selection.
3. t = period of output waveform.

Figure 1. shows a generic block diagram for connecting a prescaler to a PLL device
that supports dual modulus control. Application note AN535 decribes using a two-
modulus prescaler technique.By using prescaler higher frequencies can be achieve
than by a single CMOS PLL device.
