| ML12019 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. * 225 MHz Toggle Frequency * Low-Power 7.5 mA Maximum at 5.5 V * Control Input is Compatible with Standard Motorola or Lansdale CMOS Synthesizers * Emitter Follower Output * Operating Temperature Range TA = -40 to 85C P-DIP 8 SO 8 8 1 P DIP 8 = PP PLASTIC PACKAGE CASE 626-04 SO 8 = -5P PLASTIC PACKAGE CASE 751 (SO-8) CROSS REFERENCE/ORDERING INFORMATION LANSDALE PACKAGE MOTOROLA MC12019P MC12019D ML12019PP ML12019-5P Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.

Generic block diagram showing prescaler connection to PLL device Prescaler Fout Fin PLL ML145146 ML145158 ML145159 ML12019 MC in MC VCO Loop Filter 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.
