3F COMMUNICATIONS CIRCUITS (continued) *>LL FREQUENCY SYNTHESIZERS fotorola offers a choice of phase-locked loop components rang- ig from complete, functional PLL circuits for dedicated appli- ations to a wide selection of basic PLL circuit elements. Full- inction phase-locked loops include devices having serial and arallel inputs, as well as 4-bit data inputs for MPU data-bus iterfacing. Options include single or dual-modulus capability, .. For General Purpose Applications his family of PLL frequency synthesizers is fabricated with 4otorola CMOS technology for very low power consumption. designed for a wide variety of applications, the familly consists CATV AM/FM Radio Two-Way Radio TV Tuning Zommon characteristics for the family include: 3.0 to 9.0 Vdc Supply Range On- or Off-Chip Reference Oscillator Operation Lock Detect Signal Single-Ended or Double-Ended Error Signal Option Scanning Receivers Amateur Radio transmit/receive offsets, choice of phase detectors and choice of reference-divider integer values. Basic PLL building-block circuits include a large variety of counters and prescalers and other integral functions such as oscillators, phase detectors and control circuits. of individual devices with a wide range of inputs and divider options that make each device uniquely qualified for a specific end use. Typical applications include: The specific variations for the individual family members are given in the following table: MC145145-1/MC145146-1 MC145151-1/MC145152-1 MC145155-1|MC145156-1 MC145157-1/MC145158-1 MC145159-1 Divider Programming 4-Bit Data Bus Parallel Serial Modulus Single Dual Single Dual Single Dual Single Dual N (N/A) Divider Bits 14 (10/7) 14 (10/6) 14 (10/7) 14 (10/7) Roference Divider Bits 12 re" ven ten 14 see veState) Yes No Yes Double-Ended PD(out) Yes No -ock Detect Output Yes 3and-Switch Outputs No No ackage (pins) ee ee ee 28 18 | 20 16 16 20 otes: sample & hold analog phase detector **8 limited number of selectable values MOTOROLA EUROPEAN MASTER SELECTION GUIDE 2-39
