SP5769 - 3GHz I2C Bus Synthesiser

General Description

The SP5769 contains all the elements necessary, with the exception of a frequency reference, loop filter and external high voltage transistor, to control a varactor tuned local oscillator, so forming a complete PLL frequency synthesised source.

Key Features

  • G Complete 3.
  • 0 GHz Single Chip System G Optimised for Low Phase Noise, with Comparison G G G G G G G G G G G Ordering Information SP5769A/KG/MP1S (Tubes) SP5769A/KG/MP1T (Tape and Reel) SP5769A/KG/QP1S (Tubes) SP5769A/KG/QP1T (Tape and Reel) size equal to the loop comparison frequency and no prescaler phase noise degradation over the full RF operating range. The comparison frequency is obtained either from an on-chip crystal controlled oscillator, or from an external source. The oscillator.

SP5769 3GHz I2C Bus Synthesiser Preliminary information DS4878 Issue 4.0 October 1999 Features G Complete 3ยท0 GHz Single Chip System G Optimised for Low Phase Noise, with Comparison G G G G G G G G G G G Ordering Information SP5769A/KG/MP1S (Tubes) SP5769A/KG/MP1T (Tape and Reel) SP5769A/KG/QP1S (Tubes) SP5769A/KG/QP1T (Tape and Reel) size equal to the loop comparison frequency and no prescaler phase noise degradation over the full RF operating range. The comparison frequency is obtained either from an on-chip crystal controlled oscillator, or from an external source. The oscillator frequency, fREF, or phase comparator frequency, fCOMP, can be switched to the REF/ COMP output providing a reference for a second frequency synthesiser.
