Integrated Circuit
Phase Lock Loop (PLL) Stereo Decoder
(BTSC System)
Description:
The NTE7116 is a phase lock loop (PLL) stereo decoder in a 20–Lead DIP type package designed
primarily for low cost stereo decoding in a low–to–medium–line TV. The MUX input (Pin1) is a low
impedance current input, the gain of the input amplifier is therefore determined by the external resistor
R1. All characteristics are measured with R1 = 47kΩ. 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 7V to 16V.
Features:
D Wide Supply Voltage Range
D Automatic Mono/Stereo Switching (Pilot Presence Detector)
D LED Driver for Stereo Indicator
D Smooth Mono/Stereo Control
D Matrix and Two Amplifiers for Left and Right Output Signals
D A Source Selector to Switch between the MUX Signal and an External Signal
D Mute Circuit for 60dB Muting of the Output Level
D External De–Emphasis Control of (L, R) and (L – R)
D 6dB Fixed Attenuation of (L – R) with respect to (L + R) Prior to Matrix
D All Pins are Protected Against Electrostatic Discharge (ESD)
