Integrated Circuit  
Phase–Frequency Detector  
Description:  
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 phase–locked 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.
