ML12040 Phase–Frequency Detector Legacy Device: Motorola MC12040 The ML12040 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 ML12149), it is useful in a broad range of phase–locked loop applications.
