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. The MC145106 has circuitry for a 10.24 MHz oscillator or may operate with an external signal. The circuit provides a 5.12 MHz output signal, which can be used for frequency tripling. A 29 programmable divider divides the input signal frequency for channel selection. The inputs to the programmable divider are standard ground–to–supply binary signals. Pull–down resistors on these inputs normally set these inputs to ground enabling these programmable inputs to be controlled from a mechanical switch or electronic circuitry.
The phase detector may control a VCO and yields a high level signal when input frequency is low, and a low level signal when input frequency is high. An out–of–lock signal is provided from the on–chip lock detector with a “0” level for the out–of–lock condition.

This device contains circuitry to protect the inputs against damage due to high static volt­ages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation it is recommended that Vin and V

PLL SYNTHESIZER APPLICA TIONS
The MC145106 is well suited for applications in CB radios because of the channelized frequency requirements. A typi­cal 40 channel CB transceiver synthesizer, using a single crystal reference, is shown in Figure 3 for receiver IF values of 10.695 MHz and 455 kHz.
In addition to applications in CB radios, the MC145106 can be used as a synthesizer for several other systems. Various frequency spectrums can be achieved through the use of proper offset, prescaling, and loop programming techniques. In general, 300 – 400 channels can be synthesized using a single loop, with many additional channels available when multiple loop approaches are employed. Figures 4 and 5 are examples of some possibilities.
In the aircraft synthesizer of Figure 5, the VHF loop (top) will provide a 50 kHz, 360 channel system with 10.7 MHz R/T offset when only the 11.0500 MHz (transmit) and
12.1200 MHz (receive) frequencies are provided to mixer #1. When these signals are provided with crystal oscillators, the result is a three crystal 360 channel, 50 kHz step synthesizer. When using the offset loop (bottom) in Figure 5 to provide the indicated injection frequencies for mixer #1 (two for transmit and two for receive) 360 additional channels are possible. This results in a 720–channel, 25 kHz step synthesizer which requires only two crystals and provides R/T offset capability. The receive offset 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 receive IF (10.7 MHz) for channels having identical receive/transmit frequencies (sim­plex), and is (10.7 – 4.6 = 6.1) MHz for duplex channels. Car­rier modulation is introduced in the loop during transmit.
