3.5 Bluetooth Section Description (M601)

1.General description

ARM-450-2CSP(M601) is a Bluetooth module. The Bluetooth system consists of a radio section and

a baseband link control section. It consists of Bluetooth Transceiver chip, a EEPROM, a X-tal, a

Balun and a band pass filter. And it is surface mountable type for mobile applications. It provides

fully compliant Bluetooth system for data and voice communications. Physical interface to host

UART can support full Bluetooth data rate 723.2k/57.6kbps. A-Law, µ-Law,13bit or 16bit linear

PCM, 8k sample/sec synchronous bidirectional audio interface is available.

Bluetooth section has a chip antenna (ANT1)

2.Bluetooth chip (transceiver)

BC03-CSP is a single chip radio and baseband chip for Bluetooth wireless technology 2.4GHz

system. Supports power class 2 radios without the need for an external power amplifier or Tx/Rx

switch. The transmitter up-converts the baseband information to the frequency-modulated carrier.

Frequency hopping and bursting are performed at this level. For transmission, these range from

direct VCO Modulation to IQ mixing at the final RF. In the receiver, a conventional frequency

discriminator or IQ down-conversion combined with analog-to–digital conversion is consisted
