TEA5581 TEA5581T The TEA5581 PLL stereo decoder is for car and medium-fi radios.It incorporates all the

provided by the TEA5580 together with a source selector, muting circuit and output amplifiers with adjustable gain. It also features a switch for radio or cassette function and a 228 kHz voltage-controlled oscillator (VCO) that is locked to the 19 kHz stereo pilot tone by a phase-locked loop (PLL) system. Subcarrier frequencies of 19, 38, 57 and 114 kHz are regenerated via I2L logic from the VCO output. The PLL phase detector suppresses phase distortion due to the 57 kHz pilot tone from the Germ.
