1. General description
ARM-450-2CSP(M1) 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
