Description



Features:

The NTE974 consists of two digital phase detectors, a charge pump, and an amplifier.  In combination with a voltage controlled multivibrator, it is useful in a broad range of phaselocked loop applications. The circuit accepts MTTL waveforms at the R and V inputs and generates an error voltage that is pro-portional to the frequency and/or phase difference of the input signals.  Phase detector #1 is intended for use in systems requiring zero frequency and phase difference at lock.  Phase detector #2 is used if quadrature lock is desired.  Phase detector #2 can also be used to indicate that the main loop, utiliz-ing phase detector #1, is out of lock.
