TDA8735 - PLL frequency synthesizer

General Description

The TDA8735 is a single-chip PLL synthesizer designed for satellite receivers.

The device can be set to two different addresses which can be used in applications where independently tuned VCOs are required.

Key Features

  • Complete 30 MHz single-chip tuning system.
  • Loop amplifier included.
  • 2-level current amplifier (charge pump) for adjusting the loop gain.
  • A powerful digital memory phase detector.
  • Programmable reference frequencies of 1 kHz, 10 kHz or 25 kHz.
  • I2C-bus interface.
  • Programmable address select input.
  • Software controlled switch output.
