NTE743
Integrated Circuit
Phase Lock Loop (PLL) Stereo Decoder
Description:
The NTE743 requires only a single, non critical resistive tuning adjustment. This device derives left
and right audio channels from the standard composite stereo decoder can also be used in a number
of subscription TV decoder schemes or in various proposed TV stereo systems.
Using phase–lock techniques, the subcarrier (38 KHz for FM stereo) is regenerated in phase with and
at exactly twice the frequency of the transmitted pilot signal. Switching between monaural and stereo
operation is accomplished automatically by the presence of the pilot signal.
Low–impedance emitter–follower outputs and an internal voltage regulator for increased stability
make the NTE743 suitable for both line–operated and automotive applications. It is designed to oper-
ate over a wide supply–voltage range and will function with supplies as low as 9V.
