TEA5582 Overview
The TEA5582, a 20-pin integrated phase-locked loop (PLL) stereo decoder, is designed primarily for low cost stereo decoding in a low- to medium-line TV. The MUX input (pin 1) is a low impedance current input, the gain of the input amplifier is therefore determined by the external resistor R1 (see Fig.5). All characteristics are measured with R1 = 47 kΩ.
TEA5582 Key Features
- Wide supply voltage range
- Automatic mono/stereo switching (pilot presence detector)
- LED driver for stereo indicator
- Smooth mono/stereo control
- Matrix and two amplifiers for left and right output signals
- A source selector to switch between the MUX signal and an external signal
- Mute circuit for 60 dB muting of the output level
- External de-emphasis control of (L, R) and (L
- 6 dB fixed attenuation of (L
- R) with respect to (L + R) prior to matrix
