TEA5582 - PLL stereo decoder BTSC

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.

Key Features

  • Wide supply voltage range TEA5582.
  • 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 att.

INTEGRATED CIRCUITS DATA SHEET TEA5582 PLL stereo decoder (BTSC system) Product specification File under Integrated Circuits, IC02 July 1990 Philips Semiconductors Product specification PLL stereo decoder (BTSC system) 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.
