2 Key Features
Key Features
Radio
Baseband and Software
ƒ Direct 50Ω connection to a common TX/RX antenna
ƒ Bluetooth v2.0+EDR specification compliant
ƒ Extensive built-in self-test minimises production test
time
ƒ No external trimming is required in production
ƒ Antenna matching and filtering within IC
Transmitter
ƒ +6dBm RF transmit power with level control from
on-chip 6-bit DAC over a dynamic range >30dB
ƒ Class 2 and Class 3 support without the need for an
external power amplifier or TX/RX switch
ƒ Internal programmed 4Mbit ROM for complete
system solution
ƒ 48kbyte on-chip RAM allows full speed Bluetooth
data transfer, mixed voice and data, plus full seven
slave piconet operation
ƒ Logic for forward error correction, header error
control, access code correlation, demodulation,
CRC, encryption bitstream generation, whitening
and transmit pulse shaping
ƒ Transcoders for A-law, µ-law and linear voice from
host and A-law, µ-law and CVSD voice over air
Physical Interfaces
Receiver
ƒ Integrated channel filters
ƒ Digital demodulator for improved sensitivity and
co-channel rejection
