SNOSBY1C – JUNE 1999 – REVISED DECEMBER 2015 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. 1 Functionally Similar to LM567
