2.1

FM Receiver

The receiver uses a digital low-IF architecture thatavoids the difficulties associated with directconversion while delivering lower solution costand 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-digitalconverters (ADCs), an audio DSP and a highfidelity digital-to-analog converters (DACs).
The limiter prevents overloading and limits theamount of intermodulation products created bystrong 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 andthen 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.
2.2

Synthesizer

The frequency synthesizer generates the local
oscillator signal which divide to multi-phase, thenbe 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 to115MHz.

2.3

Power Supply

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

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, eachbyte 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), andan 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 register0x02h 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 databytes 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.

producer assures process compatibility at the peak reflow profile temperatures definedin 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 thethickness and volume. The use of convection reflow processes reduces the thermal
gradients between packages. However, thermal gradients due to differences inthermal mass of SMD package may sill exist.
Note 5: Components intended for use in a “lead-free” assembly process shall be evaluatedusing 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.
