Dual Modulus Prescaler
MECL PLL COMPONENTS ÷20/21 DUAL MODULUS
SEMICONDUCTOR TECHNICAL DATA
Legacy Device: Motorola MC12019
The ML12019 is a divide by 20 and 21 dual modulus
prescaler. It will devide by 20 when the modulus control
input is HIGH and divide by 21 when the modulus control
input is LOW.

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.
