PLL stereo decoder and noise blanker
Product specification
TDA1591
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.
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.
