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 k
. 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)
