[5] Cautions concerning the use of XBUF
When the XBUF output is on (AM up conversion is being used), the XBUF signal may leak to the adjacent pins
(PD0, I/O-3), so do not use PD0 and I/O-3 for AM reception control. (Use the PD1 pin for the AM reception charge
pump.) When using PD0 and I/O-3 for FM reception control, the XBUF output must be turned off (XB data = 0).
[6] Power supply pins
To filter out noise, insert a capacitor of at least 2000 pF between the power supply pins V
DD
and V
SS
. The capacitor
must be located as close to the pins as possible.
