1 / 11 page www.lansdale.com Page 1 of 11 Issue A ML12179 500-2800 MHz Single Channel Frequency Synthesizer Legacy Device: Motorola MC12179 The ML12179 is a monolithic Bipolar synthesizer integrating the high frequency prescaler, phase/frequency detector, charge pump, and reference oscillator/buffer functions. When combined with an external loop filter and VCO, the ML12179 serves as a complete PLL subsystem. The device is designed for operation up to 2.8 GHz for high frequency applications such as CATV down converters and satellite receiver tuners. • 2.8 GHz Maximum Operating Frequency • Low Power Supply Current of 3.5 mA Typical, Including ICC and IP Current • Supply Voltage of 5.0 V Typical • Integrated Divide by 256 Prescaler • On–Chip Reference Oscillator/Buffer – 2.0 to 11 MHz Operation When Driven From Reference Source – 5.0 to 11 MHz Operation when used with a Crystal • Digital Phase/Frequency Detector with Linear Transfer Function • Balanced Charge Pump Output • Space Efficient 8–Lead SOIC • Operating Temperature Range TA = –40° to +85°C SO 8 = -5P PLASTIC PACKAGE CASE 751 (SO–8) 8 1 CROSS REFERENCE/ORDERING INFORMATION MOTOROLA SO 8 MC12179D ML12179-5P LANSDALE PACKAGE Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.
