The Following Hints are Recommended:
D C₃ = 100 nF should be very close to Pin 1 (V_DD) and
Pin 16 (GND 1)
D GND 2 (Pin 8 – analog ground) and GND 1 (Pin 16 –
digital ground) must be connected according to
Figure 6
D 4 MHz quartz must be very close to Pin 14 and Pin 15
D Components of the charge pump (C₁/R₁ for AM and
C₂/R₂ for FM) should be very close to Pin 12 with
respect to Pin 11.
