... In AM mode, radio signals are received on AMI (pin 4) and processed by the AM front-end circuitry. In addition to the receiver mode, there is a clocking mode to choose to clock the Si4730/31 from a reference clock or crystal. The receiver mode and the clocking mode are set by the POWER_UP command listed in Table 12 ...

... FM Receiver The Si4730/31 FM receiver is based on the proven Si4700/01 FM tuner. The receiver uses a digital low-IF architecture allowing the elimination components and factory adjustments. The Si4730/31 integrates a low noise amplifier (LNA) supporting the worldwide FM broadcast band (76 to 108 MHz). An automatic gain control (AGC) circuit controls the gain of the LNA to optimize sensitivity and rejection of strong interferers ...

... SCLK. For read operations, the control word is followed by a delay of one-half SCLK cycle for bus turn-around. Next, the Si4730/31 will drive the 16-bit read data word serially on SDIO, changing the state of SDIO on each rising edge of SCLK. A transaction ends when the user sets SEN high, then pulses SCLK high and low one final time ...
