CLARION M10 SERIES STRUCTURE
M10 SERIES USER’S MANUAL PAGE 5
AUI/FIFO Interface & Control: provides fast-in-fast-out buffer
management using TX/RX FIFO to minimize the degradation of the
throughput.
TX/RX FIFO: FIFO RAM managed by AUI/FIFO Interface & Control.
FEC Encoder/Decoder: Encoder and a decoder for efficient forward
error correction.
MODEM: generates baseband transmission signals corresponding to the
uploaded data stream or a control data generated by the Main µP. It also
regenerates the received data bit stream corresponding to the output of an
A/D Converter.
RF Modulator: modulates the IF (Intermediate Frequency) carrier by the
output of the MODEM.
Up/Down Converter: up-converts the modulated RF signal of the RF
Modulator to radio transmission signals in the 2.4 GHz band. It also down-
converts incoming RF signals of the 2.4 GHz band to IF signals.
Power Amp: amplifies the 2.4 GHz band signals up to transmit power.
RF SW: switches the signal flow from an antenna to a receiver or from the
Power Amp to the antenna.
Diversity SW: switches the antenna to use the internal antenna or the
external antenna, controlled by the Main µP to improve the reception under
the extreme fading environment.
Ext. Ant. port: The external antenna connects to this port. RF signals of
2436 MHz are transmitted or received. The connector type is a SMA
female.
LNA (Low Noise Amplifier): reduces the noise figure of the receiver to
obtain sufficient sensitivity.
Local OSC: provides local signals fed to the Up/Down Converter, to the
RF Modulator and to the Down Converter.
IF Amp: amplifies the IF (Intermediate Frequency) signal of 487 MHz,
enough to be handled by the A/D Converter.
