TEA5880TS
Integrated FM stereo radio IC for host processor tuning
5. Block diagram
Depending on the antenna design the filter components at pins 1 and 2 may not be necessary. The only two remaining coils connected to pin
17 to 20 can be replaced by printed-circuit board traces that will fit underneath the TEA5880TS resulting in a design without any external
components; see Section 14 for details on the printed-circuit board coils.
