The LMC567CM/NOPB is a general purpose low power Tone Decoder which is functionally similar to the industry standard LM567. It consists of a twice frequency voltage-controlled oscillator (VCO) and quadrature dividers which establish the reference signals for phase and amplitude detectors. The phase detector and VCO form a phase-locked loop (PLL) which locks to an input signal frequency which is within the control range of the VCO. When the PLL is locked and the input signal amplitude exceeds an internally pre-set threshold, a switch to ground is activated on the output pin. External components set up the oscillator to run at twice the input frequency and determine the phase and amplitude filter time constants.

• Low supply current drain
• No increase in current with output activated
• High oscillator stability
• Ground-referenced input
• Hysteresis added to amplitude comparator
• Out-of-band signals and noise rejected
• Green product and no Sb/Br
