TSA5055T - 2.65 GHz bidirectional I2C-bus controlled synthesizer

General Description

The TSA5055T is a single-chip PLL frequency synthesizer designed for satellite TV tuning systems.

It may be used with a symmetrical input (pins 13 and 14) or with an asymmetrical input (pin 13).

Key Features

  • Complete 2.65 GHz single-chip system.
  • Low power 5 V, 60 mA.
  • I2C-bus programming.
  • In-lock flag.
  • Varicap drive disable.
  • Low radiation.
  • 5-level Analog to Digital Converter (ADC).
  • Address selection for Picture-In-Picture (PIP), DBS tuner, etc.
  • 6 controllable outputs, 4 bidirectional.
  • Power-down flag.
  • Available in SOT109-1 (SO16) package.
  • Symmetrical or asymmetrical drive.
