Figure 3-1. RDA5800 FM Tuner Block Diagram 3.1 FM Receiver The PGA amplifies the mixer output IF signal and then digitized with ADCs. The DSP core finishes the channel selection, FM demodulation, stereo MPX decoder and output audio signal. The MPX decoder can autonomous switch from stereo to mono to limit the output noise. The DACs convert digital audio signal to analog and change the volume at same time. The DACs has low-pass feature and -3dB frequency is about 30 KHz. 3.2 Synthesizer
The receiver uses a digital low-IF architecture that avoids the difficulties associated with direct conversion while delivering lower solution cost and reduces complexity, and integrates a low noise amplifier (LNA) supporting the FM broadcast band (76 to 108MHz), a quadrature image-reject mixer, a programmable gain control (PGA), a high resolution analog-to-digital converters (ADCs), an audio DSP and a highfidelity digital-to-analog converters (DACs). The LNA has differential input ports (LNAP and LNAN) and supports any input port by set according registers bits (LNA_PORT_SEL[1:0]). The LNA default input resistance is 150 Ohm under single or dual input mode. It default input common mode voltage is GND. The limiter prevents overloading and limits the amount of intermodulation products created by strong adjacent channels. The quadrature mixer down converts the LNA output differential RF signal to low-IF, it also has image-reject function.
The frequency synthesizer generates the local oscillator signal which divide to quadrature, then be used to downconvert the RF input to a constant low intermediate frequency (IF). The synthesizer reference clock is 32.768 KHz. The synthesizer frequency is defined by bits CHAN[9:0] with the range from 76MHz to 108MHz.

SEN Input to RST
The RDA5800 selects three-wire or I2C control interface in reset process. Setting RST pin low after power up will reset the chip to initial state. Setting RST pin high will bring the chip out of reset. Setting SEN low on the rising edge of RST will select three-wire control interface, and setting SEN high on the rising edge of RST will select I2C control interface.
Table 3-2 I2C Reset Timing Characteristics
When need, the RDA5800 could enter into a powerdown mode to reduce power consumption, with software setting the ENABLE bit low. In powerdown mode, analog and digital circuitry are both disabled, while maintaining register configuration and keeping control interface active. The RDA5800 could enter back into normal mode by setting the ENABLE bit high, and resume normal working. Details refer to RDA5800 Programming Guide. 3.5 Control Interface
Figure 3-1. Three-wire Interface Reset Timing Diagram
The RDA5800 supports three-wire and I2C control interface. User could select either of them to program the chip. The three-wire interface is a standard SPI interface. It includes three pins: SEN, SCLK and SDIO. Each register write is 25-bit long, including 4-bit high register address, a r/w bit, 4-bit low register address, and 16-bit data (MSB is the first bit). RDA5800 samples command byte and data at posedge of SCLK. Each register read is also 25-bit long, including 4-bit high register address, a r/w bit, 4-bit low register address, and 16-bit data (MSB is the first bit) from RDA5800. The turn around cycle between command byte from MCU and data from RDA5800 is a half cycle. RDA5800 samples command byte at posedge of SCLK, and output data also at posedge of SCLK. The I2C interface is compliant to I2C Bus Specification 2.1. It includes two pins: SCLK and SDIO. A I2C interface transfer begins with START condition, a command byte and data bytes, each byte has a followed ACK (or NACK) bit, and ends with STOP condition. The command byte includes a 7-bit chip address (0010000b) and a R/W bit. The ACK (or NACK) is always sent out by receiver. When in write transfer, data bytes is written out from MCU, and when in read transfer, data bytes is read out from RDA5800. There is no visible register address in I2C interface transfers. The I2C interface has a fixed start register address (0x02h

0x0Ah for read transfer), and an internal incremental address counter. If register address meets the end of register file, 0x3Ah, register address will wrap back to 0x00h. For write transfer, MCU programs registers from register 0x02h high byte, then register 0x02h low byte, then register 0x03h high byte, till the last register. RDA5800 always gives out ACK after every byte, and MCU gives out STOP condition when register programming is finished. For read transfer, after command byte from MCU, RDA5800 sends out register 0x0Ah high byte, then register 0x0Ah low byte, then register 0x0Bh high byte, till receives NACK from MCU. MCU gives out ACK for data bytes besides last data byte. MCU gives out NACK for last data byte, and then RDA5800 will return the bus to MCU, and MCU will give out STOP condition. Details refer to RDA5800 Programming Guide. 3.6 I2S Audio Data Interface
audio interface. The interface is fully compliant with I2S bus specification. When setting I2SEN bit high, RDA5800 will output SCK, WS, SD signals from GPIO3, GPIO1, GPIO2 as I2S master and transmitter, the sample rate is 42Kbps. 3.7 GPIO Outputs
The RDA5800 has three GPIOs. The function of GPIOs could programmed with bits GPIO1[1:0], GPIO2[1:0], GPIO3[1:0] and I2SEN. If I2SEN is set to low, GPIO pins could be programmed to output low or high or high-Z, or be programmed to output interrupt and stereo indicator with bits GPIO1[1:0], GPIO2[1:0], GPIO3[1:0]. GPIO2 could be programmed to output a low interrupt (interrupt will be generated only with interrupt enable bit STCIEN is set to high) when seek/tune process completes. GPIO3 could be programmed to output stereo indicator bit ST. Constant low, high or high-Z functionality is available regardless of the state of VA and VD supplies or the ENABLE bit.
The RDA5800 supports I2S (Inter_IC Sound Bus)
