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)
