FM/IF system and microcomputer-based tuning interface

GENERAL DESCRIPTION\nThe 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 m • 4-stage symmetrical IF limiting amplifier\n• Software selectable AM or FM input\n• Symmetrical quadrature demodulator\n• Single-ended LF output stage\n• D.C. output level determined by the input signal\n• Semi-adjustable AM and FM level voltage\n• Multi-path detector/rectifier/amplifier circuitry\;

Antenna diversity circuit

GENERAL DESCRIPTION\nIntended for multi-antenna FM car radio reception (antenna diversity system), the TEA6101/T selects the most favourable signal from one of up to four antennae. Founded upon audible signal disturbance the criteria are\nderived from two signals: high frequency components (e.g. spi • Ability to switch between up to four antennae\n• Switching signal derived from two signals: the audio and the level signals\n• Floating switching threshold adjusts switching rate to prevailing circumstances:\n– increasing threshold due to excessive noise\n– increasing threshold due to numerous lev;
