TEA6100 - FM/IF system and microcomputer-based tuning interface

General Description

The TEA6100 is a FM/IF system circuit intended for microcomputer controlled radio receivers.

The circuit includes highly sensitive analogue circuitry.

The digital circuitry, including an I2C bus, controls the analogue circuitry and the AM/FM tuning and stop information for the microcomputer.

Key Features

  • 4-stage symmetrical IF limiting amplifier.
  • Software selectable AM or FM input.
  • Symmetrical quadrature demodulator.
  • Single-ended LF output stage.
  • D. C. output level determined by the input signal.
  • Semi-adjustable AM and FM level voltage.
  • Multi-path detector/rectifier/amplifier circuitry.
  • 3-bit level information and 3-bit multi-path information.
