  • Method For Adjusting The Output Frequency Of A Frequency Synthesizer

    view source
  • US Patent:
    54989981, Mar 12, 1996
  • Filed:
    Nov 16, 1992
  • Appl. No.:
    7/976768
  • Inventors:
    James K. Gehrke - Lake in the Hills IL
    Robert J. Sarocka - Lombard IL
  • International Classification:
    H04B 140
    H03L 700
  • US Classification:
    331 17
  • Abstract:
    Adjustment of the output frequency of a frequency synthesizer can be optimized in the following manner. Once a frequency adjustment request is detected, which indicates a selected frequency, a frequency difference is calculated between the selected frequency and the present frequency. A frequency scaling factor is then determined. Once the frequency difference and the frequency scaling factor are determined, a frequency adjustment time is calculated based on a proportional relationship between the frequency difference and the frequency scaling factor. The bandwidth of a multi-bandwidth filter is adjusted to a second bandwidth for the duration of the calculated frequency adjustment time. The output frequency of the frequency synthesizer is adjusted from the present frequency to the selected frequency prior to the expiration of the frequency adjustment time. Upon expiration of the frequency adjustment time, the bandwidth of the multi-bandwidth filter is adjusted from the second bandwidth to the first bandwidth.

  • US Patent:
    52574091, Oct 26, 1993
  • Filed:
    Oct 18, 1991
  • Appl. No.:
    7/779553
  • Inventors:
    Robert J. Sarocka - Lombard IL
    David D. Neperud - Roselle IL
    Peter P. Walter - Schaumburg IL
    Tim J. Manczko - Hanover Park IL
    David H. Spensley - West Chicago IL
  • Assignee:
    Motorola, Inc. - Schaumburg IL
  • International Classification:
    H04B 140
  • US Classification:
    455 76
  • Abstract:
    This disclosure discusses a programmable frequency synthesizer arrangement having programming feedback capability used to avoid undesirable operation due to random hard and soft faults. The arrangement operates by supplying appropriate programming information, receiving the same, subject to random hard or soft faults, and, in response, directing the operation of a frequency synthesizer (10). The feedback capability is accomplished by generating a feedback signal (35, 36) indicative of the programming information as applied to the frequency synthesizer, generating a reference signal representative of the appropriate programming information, comparing the two signals, and blocking undesirable operation of the frequency synthesizer if the comparison indicates the occurrence of a random hard or soft fault. Further disclosed is a wireless communications transceiver with the programmable frequency synthesizer arrangement.
