NTE974 Integrated Circuit Phase-Frequency Detector
Description: NTE974 consists digital phase detectors, charge pump, amplifier. combination with voltage controlled multivibrator, useful broad range phase-locked loop applications. circuit accepts MTTL waveforms inputs generates error voltage that proportional frequency and/or phase difference input signals. Phase detector intended systems requiring zero frequency phase difference lock. Phase detector used quadrature lock desired. Phase detector also used indicate that main loop, utilizing phase detector lock.
