| MCH12140, MCK12140 Phase-Frequency Detector The MCH/K12140 is a phase frequency-detector intended for phase-locked loop applications which require a minimum amount of phase and frequency difference at lock. When used in conjunction with high performance VCO such as the MC100EL1648, a high bandwidth PLL can be realized. The device is functionally compatible with the MC12040 phase-frequency detector with the maximum frequency extending to 800 MHz. When the Reference (R) and VCO (V) inputs are unequal in frequency and/or phase, the differential UP (U) and DOWN (D) outputs will provide pulse streams which when subtracted and integrated provide an error voltage for control of a VCO. See AND8040 for further information. The device is packaged in a small outline, surface mount 8-lead SOIC package. There are two versions of the device to provide I/O compatibility to the two existing ECL standards. The MCH12140 is compatible with MECL 10H logic levels while the MCK12140 is compatible to 100 K ECL logic levels. This device can also be used in +5.0 V systems.

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: Fv > Fr R lags V U R leads V Fv < Fr VOH VOH - VOL 2 VOH VOH - VOL 2 VOH - VOL 2 p R lags V in phase When the R and V inputs are equal in frequency and the phase of R lags that of V the U output will stay HIGH while the D output will pulse from HIGH to LOW. The magnitude of the pulse will be proportional to the phase difference between the V and R inputs reaching a minimum 50% duty cycle under a 180 out of phase condition. The signal on D indicates to the VCO to decrease in frequency to bring the loop into lock. V frequency > R frequency When the frequency of V is greater than that of R the 12140 behaves in a similar fashion as above. Again the signal on D indicates that the VCO frequency must be decreased to bring the loop into lock. R leads V in phase -2p -p D p 2p -2p -p U-D p When the R and V inputs are equal in frequency and the phase of R leads that of V the D output will stay HIGH while the U output pulses from HIGH to LOW. The magnitude of the pulse will be proportional to the phase difference between the V and R inputs reaching a minimum 50% duty cycle under a 180 out of phase condition. The signal on U indicates to the VCO to increase in frequency to bring the loop into lock. V frequency < R frequency 2p -2p -p 2p VOL - VOH 2 Figure 2. Average Output Voltage vs. Phase Difference When the frequency of V is less than that of R the 12140 behaves in a similar fashion as above. Again the signal on U indicates that the VCO frequency must be decreased to bring the loop into lock. From Figure 2 when V and R are at the same frequency and in phase the value of U - D is zero thus providing a zero error voltage to the VCO. This situation indicates the loop is in lock and the 12140 action will maintain the loop in its locked state. http://onsemi.com 3 MCH12140, MCK12140 PACKAGE DIMENSIONS SOIC-8 D SUFFIX CASE 751-07 ISSUE AB -X- A 8 5 NOTES: 1.
