Additional testing information is available in “AN569: Si4831/35-DEMO Board Test Procedure.” Volume = maximum for all tests. Tested at RF = 98.1 MHz. 2. To ensure proper operation and receiver performance, follow the guidelines in “AN555: Si483x-B Antenna, Schematic, Layout, and Design Guidelines.” Silicon Laboratories will evaluate schematics and layouts for qualified customers. 3. Frequency is 76~109 MHz. 4. Guaranteed by characterization. 5. VEMF =1 mV. 6. FMOD = 1 kHz, MONO, and L = R unless noted otherwise. 7. f = 22.5 kHz. 8. |f2 – f1| > 2 MHz, f0 =2xf1 – f2. 9. BAF = 300 Hz to 15 kHz, A-weighted. 10. At LOUT and ROUT pins. 11. f = 75 kHz. |
