NTE790 Dual Chroma Demodulator PDIP-14

Info as pdf-file

Description:
The NTE790 has 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 a fixed relationship of amplitude and phase nominally equal DC voltage levels. The outputs of the NTE790 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.
