Order this document by MC12181/D 125-1000 MHz Frequency Synthesizer The MC12181 is a monolithic bipolar synthesizer integrating a high performance prescaler, programmable divider, phase/frequency detector, charge pump, and reference oscillator/buffer functions. The device is capable of synthesizing a signal which is 25 to 40 times the input reference signal. The device has a 4–bit parallel interface to set the proper total multiplication which can range from 25 to 40. When combined with an exte.

The device is capable of synthesizing a signal which is 25 to 40 times the input reference signal. The device has a 4–bit parallel interface to set the proper total multiplication which can range from 25 to 40. When combined with an external passive loop filter and VCO, the MC12181 serves as a complete PLL subsystem. • 2.7 to 5.5 V Operation • Low power supply current of 4.25 mA typical • On chip reference oscillator/buffer supporting wide frequency operating range from 5 to 25 MHz • 4–bit parallel interface for programming divider (N = 25 .... 40) • Wide 125 – 1000 MHz frequency of operation • Digital phase/frequency detector with linear transfer function • Balanced Charge Pump Output • Space efficient 16.
