NTE713
Integrated Circuit
Chroma Demod
Description:
The NTE713 is a monolithic integrated circuit in a 14–Lead DIP type package that contains two sets
of synchronous detectors with matrix circuits to achieve the R–Y, G–Y, and B–Y color difference output
signals. The chroma input signal is applied to Pin3 and Pin4 while the oscillator injection signal is
applied to Pin6 and Pin7. The color difference signals, after matrix, have fixed a relationship of ampli-
tude and phase nominally equal DC voltage levels. The outputs of the NTE713 are suitable for driving
high level color difference or R, G, B output amplifiers. Emitter–follower output stages used to drive
the high level color amplifiers have short–circuit protection.
Features:
D Synchronous Detector with Color Difference Matrix
D Emitter–Follower Output Amplifier with Short–Circuit Protection
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
