Note 1:
DIS% =
100.(V12 + V22 +. . . + Vn2)1/2
(VOC2 + VOR2)1/2
a. V1 . . . Vn are the intermodulation or the harmonic frequencies in the 500 Hz to 3400 Hz band.
b. VOC and VOR are the individual frequency components of the DTMF signal.
AC ELECTRICAL CHARACTERISTICS(All Voltages referenced to GND. VCC = 1.8 V to 5.5 V,
TA = -20 to +70°C, FOSK = 480 KHz)
