MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145191/D ARCHIVE INFORMATION ARCHIVE INFORMATION 1.1 GHz PLL Frequency Synthesizer Includes On–Board 64/65 Prescaler The MC145191 is a single–package synthesizer with serial interface capable of direct usage up to 1.1 GHz. A special a.

Features

a single
  –ended current source/sink phase detector output and a double
  –ended phase detector output. Both phase detectors have linear transfer functions (no dead zones). The maximum current of the single
  –ended phase detector output is determined by an external resistor tied from the Rx pin to ground. This current can be varied via the serial port. The MC145191 has phase/frequency detectors optimized for single
  –supply systems of 5 V ± 10%. The part includes a differential RF input which may be operated in a single
  –ended mode. Also featured are on
  –board support of an external crystal and a program.
