PLL stereo decoder (BTSC system) TEA5582

GENERAL DESCRIPTION

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. The de-emphasis of (L, R) and (L-R) can be chosen by means of external capacitors and resistors. The supply voltage range of the device is from 7 V to 16 V.

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 − R)

• 6 dB fixed attenuation of (L − R) with respect to (L + R)

prior to matrix

• All pins are protected against Electrostatic Discharge (ESD)
