1 Intruduction
RoyalTek RTM-6000 is the RDS-TMC demodulator module
using Silicon Lab Si4703 chip and Silicon Lab C8051F331 MCU.
RTM-6000 has a low power consumption and can operate at a
low supply voltage. The module demodulates the RDS-TMC
in FM band from 87.5MHz to 108MHz. The block data and
status information are available via I²C bus. Then pass
through C8051F331 (MCU) transmission CMOS level (+3.3V) to
communicate with device. The smallest form factor and
miniature design is the best choice to be embedded in a
portable device like PDA, PND and navigation such as personal locators, speed camera
detectors and vehicle locators. The module can be used on supporting navigation and traffic
application.

RTM-6000 Operational Manual
(1)GND
GND provides the ground for RTM-6000 Module.
(2)Power:
Connect V_IN_3V3 pin to DC 2.9~3.6V.The power supply must add Bead and
bypassing capacitor(22~47uF).It can reduce the Noise from power supply and increase
power stability.
(3)TX
This is the main transmitting channel and is used to output user application software.
(4) RX
This is the main receiver channel and is used to receive software commands to user
application software.
(5)AUDIO_L/R
The two pin contains the Audio of the left/right channel directly out of the Si4703.
(6)FM_ANT
This pin is FM Antenna input pin. It is suggested to use 50 ohm trace from FM-ANT pin
to FM antenna connector.

6 Layout Note:
(1) The trace connected to FM_IN should be 50 ohm.
(2) It is recommended to add Bead and bypass capacitor above 10~33uF to reduce power
noise.
(3) The system’s EMI or noise is recommended to reduce first which efficiently boost TMC
performance.
(4) Please refer to the recommend pad for connecting well.
