TEA6100
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.
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
Signal dependent 'soft' muting circuit; externally
adjustable
Reference voltage output (FM mode only)
8-bit AM/FM frequency counter with selectable counter
resolution
Possibility to measure the AM IF frequency at 460 kHz
(250 Hz resolution) and 10,7 MHz (500 Hz resolution)
Reference frequency can be directly connected to the
reference frequency output of a frequency synthesizer
(TSA6057, 40 kHz) .
