TSA5518M - 1.3 GHz bidirectional I2C-bus controlled synthesizer

General Description

The device is a single chip PLL frequency synthesizer designed for TV tuning systems.

Control data is entered via the I2C-bus; five serial bytes are required to address the device, select the oscillator frequency, program the 7 output ports and set the charge-pump current.

Key Features

  • Complete 1.3 GHz single chip system.
  • Low power 5 V, 40 mA.
  • I2C-bus programming.
  • One pin crystal oscillator.
  • In-lock flag.
  • Varicap drive disable.
  • Low radiation.
  • Address selection for picture in picture (PIP), DBS tuner, and so on.
  • 5-level A/D converter.
  • 7 bus-controlled ports (4 open-collector outputs and 3 emitter follower outputs), 1 bidirectional port.
  • Power-down flag.
  • Mixer/oscillator.
