LMC567CM
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
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.
Features
