GENERAL DESCRIPTION

The TDA1591 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)

• Applicable as source selector for AM/FM/cassette switching

• Separate interference noise detector

• Integrated input low-pass filter for delayed noise blanking

• Noise blanking at MPX-demodulator outputs

• Internal voltage stabilization.
