MOTOROLA Order this document by MC145106/D MC145106/D SEMICONDUCTOR TECHNICAL DATA MC145106 MC145106 PLL Frequency Synthesizer The MC145106 MC145106 is a phase­locked 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 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 ground­to­supply binary signals. Pull­down 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 out­of­lock signal is provided from the on­chip lock detector with a "0" level for the out­of­lock condition. · · · · · · · · · · · P SUFFIX PLASTIC DIP CASE 707 18 1 DW SUFFIX SOG PACKAGE CASE 751D 20 1 ORDERING INFORMATION MC145106P MC145106P MC145106DW MC145106DW Plastic DIP SOG Package Single Power Supply Wide Supply Range: 4.5 to 12 V Provision for 10.24 MHz Crystal Oscillator 5.12 MHz Output Programmable Division Binary Input Selects up to 29 On­Chip Pull­Down Resistors on Programmable Divider Inputs Selectable Reference Divider, 210 or 211 (Including ÷ 2) Three­State Phase Detector See Application Note AN535 AN535 and Article Reprint AR254 AR254 Chip Complexity: 880 FETs or 220 Equivalent Gates See the MC145151 MC145151­2 and MC145152 MC145152­2 for Higher Performance and Added Flexibility BLOCK DIAGRAM OSCout ÷ 2out OSCin FS REFERENCE DIVIDE 29 OR 210 ÷2 Detout PHASE DETECTOR fin DIVIDE­BY­N COUNTER 29 ­ 1 P0 P1 P2 P3 P4 P5 P6 LD P7 P8 REV 4 1/99 © Motorola, Inc. 1998 MC145106 MC145106 1 MOTOROLA RF/IF DEVICE DATA ARCHIVE INFORMATION ARCHIVE INFORMATION CMOS PIN ASSIGNMENTS PLASTIC DIP 1 18 VSS fin 2 17 P0 OSCin 3 16 P1 OSCout 4 15 P2 5 14 P3 FS 6 13 P4 Detout 7 12 P5 LD 8 11 P6 P8 9 10 P7 ARCHIVE INFORMATION B 2out SOG PACKAGE VDD 1 20 VSS fin 2 19 P0 OSCin 3 18 NC OSCout 4 17 P1 5 16 P2 B 2out FS 6 15 P3 Detout 7 14 P4 LD 8 13 NC P8 9 12 P5 P7 10 11 P6 NC = NO CONNECTION MAXIMUM RATINGS (Voltages Referenced to VSS) Parameter DC Supply Voltage Input Voltage, All Inputs DC Input Current, per Pin Operating Temperature Range Storage Temperature Range MOTOROLA RF/IF DEVICE DATA Symbol Value Unit VDD ­ 0.5 to + 12 V Vin ­ 0.5 to VDD + 0.5 V I ± 10 mA TA ­ 40 to + 85 °C Tstg ­ 65 to + 150 °C 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.

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 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 LD ÷ 29/210 OSC 10.24 MHz 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 720­channel, 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. ÷2 MC145106 MC145106 5.0 kHz PHASE DETECTOR LOOP FILTER VCO BUFFER PROGRAMMABLE DIVIDER VDD 26.965 ­ 27.405 MHz (TRANSMIT) 26.510 ­ 26.950 MHz (RECEIVE) GND SWITCH WAFERS R/T BUFFER 1.365 ­ 1.805 MHz (TRANSMIT) 0.91 ­ 1.35 MHz (RECEIVE) X5 25.6 MHz MIXER 10.24 MHz TO RECEIVER 2ND MIXER 16.270 ­ 16.710 MHz RECEIVER 1ST LOCAL OSC SIGNAL MIXER Figure 3.
