Notes:
DD
1. The Si4730/31 divides the RCLK input by REFCLK_PRESCALE to obtain REFCLK. There are some RCLK
2. A frequency tolerance of ±50 ppm is required for FM seek/tune using 50 kHz channel spacing.
= 2.7 to 5.5 V, VIO = 1.5 to 3.6 V, T
frequencies between 31.130 kHz and 40 MHz that are not supported. See AN385, Table 6 for more details.
