MC12019

Dual Modulus Prescaler The MC12019 is a divide by 20 and 21 dual modulus prescaler. It will divide 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 CMOS Synthesizers Emitter Follower Output Order this document by MC12019/D MC12019 MECL PLL COMPONENTS ÷20/21 DUAL MODULUS PRESCALER SEMICONDUCTOR TECHNICAL DATA 8 1 D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) SIMPLIFIED BLOCK DIAGRAM Control Input 1 0.001 µF Signal Input 5 Signal 6 Gnd 0.001 µF 7 0.1 µF VCC ÷N / N+1 4 10 k Gnd 3 Output 8 1 P SUFFIX PLASTIC PACKAGE CASE 626 PIN CONNECTIONS IN 1 NE 2 Out 3 Gnd 4 8 NC 7 VCC 6 SGnd 5 SIN (Top View) ORDERING INFORMATION Device Operating Temperature Range Package MC12019D TA = – 40° to +85°C MC12019P SO–8 Plastic © Motorola, Inc. 1997 Rev 2 MAXIMUM RATINGS Rating Power Supply Voltag...
