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.
