... Phase-Frequency Detector The MC12040 is a phase–frequency detector intended for use in systems requiring zero phase and frequency difference at lock. In combination with a voltage controlled oscillator (such as the MC1648, MC12147, MC12148 or MC12149 useful in a broad range of phase–locked loop applications. Operating Frequency = 80 MHz Typical ...

... ELECTRICAL CHARACTERISTICS The MC12040 has been designed to meet the dc specifications shown in the test table after thermal equilibrium has been established. Outputs are terminated through a 50 ohm resistor to +3.0 V for +5.0 V tests and through a 50 ohm resistor to –2.0 V for –5.2 V tests. NOTE: For more information on using an ECL device in a +5V system, refer to Motorola Application Note AN1406/D, “ ...

... The device under test must be preconditioned before performing the ac tests. Preconditioning may be accomplished by applying pulse generator 1 for a minimum of two pulses prior to pulse gen- t– erator 2. The device must be preconditioned again when inputs to pins 6 and 9 are interchanged. The same technique applies. MC12040 Output Waveform ...

... The MC12040 is a logic network designed for use as a phase comparator for MECL–compatible input signals. It determines the “lead” or “lag” phase relationship and the time difference between the leading edges of the waveforms. Since these edges occur only once per cycle, the detector has a range of 2π ...
