Manufacturer:TI Description: The 12140 is a high speed digital circuit used as a phase comparator in an analog phase-locked loop. The device determines the lead or lag phase relationship and time difference between the leading edges of a VCO (V) signal and a Reference (R) input. Since these edges occur only once per cycle, the detector has a range of 2p radians. The operation of the 12140 can best be described using the plots of Figure 2. Figure 2 plots the average value of U, D and the difference between U and D versus the phase difference between the V and R inputs. There are four potential relationships between V and R: R lags or leads V and the frequency of R is less than or greater than the frequency of V. Under these four conditions the 12140 will function as follows: |
