When used in conjunction with the MC12147, MC12148 or MC12149 VCO, a high bandwidth PLL can be realized. The device is functionally compatible with the MC12040 phase-frequency detector, however the MOSAICTM III process is used to push the maximum frequency to 800 MHz and significantly reduce the dead zone of the detector. 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. 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 MECL10HTM logic levels while the MCK12140 is compatible to 100K ECL logic levels. This device can also be used in +5.0 V systems. Please refer to Motorola Application Note AN1406/D, "Designing with PECL (ECL at +5.0 V)" for more information.

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 2 radians. The operation of the 12140 can best be described using the plots of Figure 1. Figure 1 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: Figure 1. Average Output Voltage versus Phase Difference Fv > Fr R lags V U R leads V Fv < Fr VOH VOH - VOL 2 VOH VOH - VOL 2 VOH - VOL 2 -2 - D 2 -2 - U-D 2 -2 - 2 VOL - VOH 2 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 simlar 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 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 When the frequency of V is less than that of R the 12140 behaves in a simlar fashion as above. Again the signal on U indicates that the VCO frequency must be decreased to bring the loop into lock. From Figure 1 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.
