2 / 22 page May 1994 2 Philips Semiconductors Product specification IF amplifier/demodulator for FM radio receivers TDA1599 FEATURES • Balanced limiting amplifier • Balanced coincidence demodulator • Two open-collector stop pulse outputs for microcomputer tuning control • Simulated behaviour of a ratio detector (internal field strength and detuning dependent voltage for dynamic AF signal muting) • Mono/stereo blend field strength indication control voltage • AFC output • 3-state mode switch for FM-MUTE-ON, FM-MUTE-OFF and FM-OFF • Internal compensation of AF signal total harmonic distortion (THD) • Built-in hum and ripple rejection circuits. GENERAL DESCRIPTION The TDA1599 provides IF amplification, symmetrical quadrature demodulation and level detection for quality home and car FM radio receivers and is suitable for mono and stereo reception. It may also be applied to common front ends, stereo decoders and AM receiver circuits.
