Notes:
18
1. Place C1 close to VA and C4 close to VD pin.
2. All grounds connect directly to GND plane on PCB.
3. Pins 6 and 7 are no connects, leave floating.
4. Pin 10 is unused. Tie this pin to GND.
5. To ensure proper operation and receiver performance, follow the guidelines in “AN383: Si47xx Antenna, Schematic,
6. Pin 8 connects to the FM antenna interface.
7. Place Si4704/05-D60 as close as possible to antenna and keep the FMI traces as short as possible.
