LMC567  
Low Power Tone Decoder  
General Description  
Features  
n Functionally similar to LM567  
n 2V to 9V supply voltage range  
n Low supply current drain  
The LMC567 is a low power general purpose LMCMOS  
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 inter-  
nally 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.  
n No increase in current with output activated  
n Operates to 500 kHz input frequency  
n High oscillator stability  
n Ground-referenced input  
n Hysteresis added to amplitude comparator  
n Out-of-band signals and noise rejected  
n 20 mA output current capability
