1. The Si473x divides the RCLK input by REFCLK_PRESCALE to obtain REFCLK. There are some RCLK frequencies
2. A frequency tolerance of ±50 ppm is required for FM seek/tune using 50 kHz channel spacing and AM seek/tune in SW
between 31.130 kHz and 40 MHz that are not supported. For more details, see Table 6 of “AN332: Si47xx
