SEMICONDUCTOR TECHNICAL DATA
Legacy Device: Motorola MC12015, MC12016, MC12017
The ML12015, ML12016 and ML12017 are dual modulus 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 operated by applying a supply voltage of 5.0 Vdc ±10% at Pin
7, or by applying an unregulated voltage source from 5.5
Vdc to 9.5 Vdc to Pin 8.
• 225 MHz Toggle Frequency
• Low–Power 7.5 mA Maximum at 6.8 V
• Control Input and Output Are Compatible With
Standard CMOS
• Connecting Pins 2 and 3 Allows Driving One
TTL Load
• Supply Voltage 4.5 V to 9.5 V
• Operating Temperature Range TA = –40 to 85°C

NOTES: 1. Pin 2 connected to Pin 3.
2. tPLL = the period of time the PLL has from the prescaler rising output tranistion (50%) to the modulus control input edge transition
(50%) to ensure proper modulus selection.
3. tout = 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 twomodulus prescaler technique.By using prescaler higher frequencies can be achieve
than by a single CMOS PLL device.
