MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145106/D MC145106 PLL Frequency Synthesizer CMOS The MC145106 is a phase locked loop (PLL) frequency synthesizer constructed in CMOS on a single monolithic structure.

This synthesizer finds applications in such areas as CB and FM transceivers.

The device contains an oscillator/amplifier, a 210 or 211 divider chain for the oscillator signal, a programmable divider chain for the input signal, and a phase detector.

145106P Features

* fset value is determined by the 11.31 MHz crystal frequency and is 10.7 MHz for the example. The VHF marine synthesizer in Figure 4 depicts a single loop approach for FM transceivers. The VCO operates on frequency during transmit and is offset downward during receive. The offset corresponds to the r
