The NTE874 is a monolithic bipolar/I2L integrated circuit digital sync system designed for use in consumer TV applications for color/monochrome receivers or monitors. This device takes the composite video input signal in combination with the onchip masterscan oscillator to provide both horizontal drive and vertical deflection output signals. Other onchip functions include sync separator, horizontal APC, horizontal/vertical countdown circuitry, vertical ramp generator, and horizontal drive circuit (PulseWidth Modulator). The NTE874 features dualmode operation and accepts either standard or nonstandard video signals. An automatic moderecognition system forces the operation into the asynchronous mode for nonstandard sync signals.
