24. The lower limit of audio bandwidth depends on the value of the capacitor at pin 6. A value of CAFD = 470 nF leads to
fAF(3 dB) ≈ 20 Hz and CAFD = 220 nF leads to fAF(3 dB) ≈ 40 Hz.
25. The reference input pin 15 is able to operate as a 1-pin crystal oscillator as well as an input terminal with external
reference signal, e.g. from the tuning system.
26. The value of Cx determines the accuracy of the resonance frequency of the crystal. It depends on the type of crystal
used.
