LM567/LM567C
Tone Decoder
General Description
The LM567 and LM567C are general purpose tone decoders
designed to provide a saturated transistor switch to ground
when an input signal is present within the passband. The cir-
cuit consists of an I and Q detector driven by a voltage con-
trolled oscillator which determines the center frequency of
the decoder. External components are used to indepen-
dently set center frequency, bandwidth and output delay.
