1. All specifications for the Si4708 unless otherwise noted.
2. Refer to Register 02h, "Power Configuration" on page 21 for ENABLE bit description.
3. The LNA is automatically switched to higher current mode for optimum sensitivity in low SNR conditions.
4. Analog and digital supply currents are simultaneously adjusted based on SNR level.
5. Stereo and/or RDS functionality are disabled at low SNR levels.
6. RDS functionality only available for Si4709.
7. Refer to Section 4.9. "Reset, Powerup, and Powerdown" on page 16.
8. For input pins SCLK, SEN, SDIO, RST, RCLK, and GPO.
9. For output pins SDIO and GPO.
