... R and V (Pins 3 and 4) Double–Ended Phase/Frequency Detector Outputs. These outputs can be combined externally to generate a loop error signal. Through use of a Motorola patented tech- nique, the detector’s dead zone has been eliminated. There- fore, the phase/frequency detector is characterized by a linear transfer function. The operation of the phase/fre- quency detector is described below and is shown in Fig- ure 19 ...

... Nominal MC145192 PD out Source Current vs Rx Resistance NOTE: The MC145192 is optimized for Rx values in the range. For example, to achieve 0 output current preferable to use a 30–k resistor for Rx and bit settings for 25% (as shown in Table 3). MOTOROLA For optimum performance should be bypassed to GND using a low–inductance capacitor mounted very close to these pins ...

... NOTE: The PD out either sources or sinks current during out–of–lock conditions. When locked in phase and frequency, the output is high impedance and the voltage at that pin is determined by the low pass filter capacitor.

... CRYSTAL OSCILLATOR CONSIDERATIONS The following options may be considered to provide a ref- erence frequency to Motorola’s CMOS frequency synthe- sizers. USE OF A HYBRID CRYSTAL OSCILLATOR Commercially available temperature–compensated crystal oscillators (TCXOs) or crystal–controlled data clock oscilla- tors provide very stable reference frequencies. An oscillator capable of CMOS logic levels at the output may be direct or dc coupled to REF in ...
