TSA5059 - 2.7GHz I2C-bus controlled low phase noise frequency synthesizer

Description

The TSA5059 is a single chip PLL frequency synthesizer designed for satellite and terrestrial tuning systems up to 2.7 GHz.

The RF preamplifier drives the 17-bit main divider enabling a step size equal to the comparison frequency, for an input frequency up to 2.7 GHz.

Features

  • Complete 2.7 GHz single chip system.
  • Optimized for low phase noise.
  • Selectable divide-by-two prescaler.
  • Operation up to 2.7 GHz with and without divide-by-two prescaler.
  • Selectable reference divider ratio.
  • Compatible with UK-DTT (Digital Terrestrial Television) offset requirements.
  • Selectable crystal/comparison frequency output.
  • Four selectable charge pump currents.
  • Four selectable I2C-bus addresses.
  • Stand.
