TEA6100

INTEGRATED CIRCUITS DATA SHEET TEA6100 FM/IF system and microcomputer-based tuning interface Product specification File under Integrated Circuits, IC01 August 1987 Philips Semiconductors Product specification 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. 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 PACKAGE OUTLINE 20-lead DIL; plastic (SOT146); SOT146-1; 1996 August 13. TEA6100 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) .
