LMC567
Low Power Tone Decoder
General Description
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.
