2. Typical Application Schematic
2.1. QFN Typical Application Schematic
Notes:
GP03/DCLK
1. Place C1 close to VA pin and C4 close to VD pin.
2. All grounds connect directly to GND plane on PCB.
3. Pins 1 and 20 are no connects, leave floating.
4. To ensure proper operation and receiver performance, follow the guidelines in “AN383: Si47xx Antenna, Schematic,
5. Pin 2 connects to the FM antenna interface.
6. Place Si4704/05-D60 as close as possible to antenna and keep the FMI traces as short as possible.
Optional: AUXIN/Digital Audio Out
OPMODE: 0x5B, 0x0B
