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 twice frequency

voltage-controlled oscillator (VCO) and quadrature dividers

which establish the reference signals for phase and ampli-

n No increase in current with output activated

n Operates to 500 kHz input frequency

n High oscillator stability

tude detectors. The phase detector and VCO form

phase-locked loop (PLL) which locks to an input signal fre-

quency 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.

n Ground-referenced input

n Hysteresis added to amplitude comparator

n Out-of-band signals and noise rejected

n 20 mA output current capability
