Figure 2-1. RDA5807M FM Tuner Block Diagram 2.1 FM Receiver noise.

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 (50 to 115MHz), a multi-phase image-reject mixer array, 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 limiter prevents overloading and limits the amount of intermodulation products created by strong adjacent channels. The multi-phase mixer array down converts the LNA output differential RF signal to low-IF, it also has image-reject function and harmonic tones rejection. 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

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. 2.2 Synthesizer

The frequency synthesizer generates the local oscillator signal which divide to multi-phase, 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 50MHz to 115MHz.

Power Supply

The RDA5807M integrated one LDO which supplies power to the chip. The external supply voltage range is 1.8-3.3 V.

RDA5807M FM Tuner V1.0

The RDA5807M is RESET itself When VIO is Power up. And also support soft reset by trigger 02H BIT1 from 0 to 1. T he RDA5807M only 2 support I C control interface bus mode.

The RDA5807M interface.

control

The I C interface is compliant to I C Bus Specification 2.1. It includes two pins: SCLK and 2 SDIO. A I C 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 RDA5807M. There is no visible 2 2 register address in I C interface transfers. The I C interface has a fixed start register address (0x02h for write transfer and 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. RDA5807M 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, RDA5807M 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 RDA5807M will return the bus to MCU, and MCU will give out STOP condition.

C (based on machine variation

is required to control the profile process but at no time will it exceed - 5 o C. The producer assures process compatibility at the peak reflow profile temperatures defined in Table –III. Note 3: Package volume excludes external terminals(balls, bumps, lands, leads) and/or non integral heat sinks. Note 4: The maximum component temperature reached during reflow depends on package the thickness and volume. The use of convection reflow processes reduces the thermal gradients between packages. However, thermal gradients due to differences in thermal mass of SMD package may sill exist. Note 5: Components intended for use in a “lead-free” assembly process shall be evaluated using the “lead free” classification temperatures and profiles defined in Table-I II III whether or not lead free.

RoHS Compliant
The product does not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE), and are therefore considered RoHS compliant.

ESD Sensitivity
Integrated circuits are ESD sensitive and can be damaged by static electricity. Proper ESD

techniques should be used when handling these devices.
