LMC567 Low-Power Tone Decoder

1 Features

3 Description

The LMC567 device is a low-power, general-purpose

LMCMOS tone decoder which is functionally similar

to the industry standard LM567. The device consists

of a twice frequency voltage-controlled oscillator

(VCO) and quadrature dividers which establish the

reference signals for phase and amplitude detectors.

•

Functionally Similar to LM567

2-V to 9-V Supply Voltage Range

Low Supply Current Drain

No Increase in Current With Output Activated

Operates to 500-kHz Input Frequency

High Oscillator Stability

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.

Ground-Referenced Input

Hysteresis Added to Amplitude Comparator

Out-of-Band Signals and Noise Rejected

20-mA Output Current Capability
