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
