Notes:
1. Additional testing information is available in “AN388: Si470x/1x/2x/3x/4x Evaluation 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 “AN383: Si47xx Antenna, Schematic,
Layout, and Design Guidelines.” Silicon Laboratories will evaluate schematics and layouts for qualified customers.
3. Guaranteed by characterization.
4. FMOD = 1 kHz, 75 µs de-emphasis, MONO = enabled, and L = R unless noted otherwise.
5. f = 22.5 kHz.
6. BAF = 300 Hz to 15 kHz, A-weighted.
7. VEMF = 1 mV.
8. Analog output mode.
9. |f2 – f1| > 2 MHz, f0 = 2 x f1 – f2. AGC is disabled.
10. f = 75 kHz.
11. At LOUT and ROUT pins.
12. At temperature (25 °C).
