GENERAL DESCRIPTION
The TDA1592 is a monolithic bipolar integrated circuit providing the stereo decoder function and noise blanking for FM car radio applications.
The device operates in a power supply range of 7.5 to 12 V.

FEATURES
• Adjustment-free voltage controlled PLL oscillator for ceramic resonator (f = 456 kHz)
• Pilot signal dependent mono/stereo switching
• Analog control of mono/stereo change over [stereo blend, Stereo Noise Controller (SNC)]
• Adjacent channel noise suppression (114 kHz)
• Pilot canceller
• Analog control of de-emphasis; High Cut Control (HCC)
• Reduced and controlled de-emphasis for AM operation (pin 7 to GND)
• Applicable as source selector for AM/FM/cassette switching
• Soft mute for silent tuning
• Separate interference noise detector
• Integrated input low-pass filter for delayed noise blanking
• Noise blanking at MPX-demodulator outputs.
