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 = 520 kHz.
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. FMOD = 1 kHz, 30% modulation, 2 kHz channel filter.
4. Analog audio output mode.
5. B AF = 300 Hz to 15 kHz, A-weighted.
6. Guaranteed by characterization.
7. See “AN388: Si470x/1x/2x/3x/4x Evaluation Board Test Procedure” for evaluation method.
8. V IN = 5 mVrms.
9. Stray capacitance on antenna and board must be < 10 pF to achieve full tuning range at higher inductance levels.

Notes:
1. The Si4736/37/38/39 divides the RCLK input by REFCLK_PRESCALE to obtain REFCLK. There are some RCLK
frequencies between 31.130 kHz and 40 MHz that are not supported. For more details, see Table 6 of “AN332: Si47xx
Programming Guide”.
2. A frequency tolerance of ±50 ppm is required for FM seek/tune using 50 kHz channel spacing and WB tune.
