Notes:
1. Additional testing information is available in âAN388: Si470x/1x/2x/3x/4x Evaluation Board Test Procedure.â
Volume = maximum for all tests. Tested at RF = 98.1 MHz.
2. To ensure proper operation and receiver performance, follow the guidelines in âAN383: Si47xx Antenna, Schematic,
Layout, and Design Guidelines.â Silicon Laboratories will evaluate schematics and layouts for qualified customers.
3. FMOD = 1 kHz, 75 µs de-emphasis, MONO = enabled, and L = R unless noted otherwise.
4. ïf = 22.5 kHz.
5. BAF = 300 Hz to 15 kHz, A-weighted.
6. Analog audio output mode.
7. Guaranteed by characterization.
8. VEMF = 1 mV.
9. |f2 â f1| > 2 MHz, f0 = 2 x f1 â f2. AGC is disabled.
10. ïf = 75 kHz.
11. Sensitivity measured at (S+N)/N = 26 dB.
12. Blocker Amplitude = 100 dBµV.
13. At temperature (25 °C).
14. At LOUT and ROUT pins.
