3. TECHNICAL BRIEF
Bluetooth Radio
- Common TX/RX teminal simplifies external matching, eliminates external antenna switch
- No external trimming is required In production
- Bluetooth v2.0 + EDR Specification compliant
Bluetooth Transmitter
- +6 dBm RF Transmit power with level control from on-chip 6-bit DAC over a dynamic range > 30dB
- Class 2 and Class 3 support without the need for an external power amplifier or TX/RX switch.
Bluetooth Receiver
- Integrated channel filters
- Digital demodulator for improved sensitivity and co-channel rejection
- Real time digitized RSSI available on HCI interface
- Fast AGC for enhanced dynamic range
- Channel classification for AFH
Synthesiser
- Fully integrated synthesizer requires no external VCO varactor diode, resonator or loop filter
- Compatible with crystals between 7.5 and 40MHz(in multiples of 250KHz) or an external clock
Audio
- Single-ended stereo analogue output
- 16-bit 48 kHz digital audio bit stream output
Baseband and Software
- Internal 48Kbyte RAM, allows full speed data transfer, mixed voice and data, and full piconet
operation, including all medium rate packet types
- Logic for forward error correction, header error control, access code correlation. CRC, demodulation,
encryption bit stream generation, whitening and transmit pulse shaping. Supports all Bluetooth
v 2.0 + EDR features incl. ESCO and AFH
- Transcoders for A-law, u-law and linear voice from host and A-law, u-law and CVSD voice over air
Physical Interfaces
- Synchronous serial interface up to 4Mbits/s for system debugging
- UART interface with programmable baud rate up to 4Mbits/s with an optional bypass mode
- USB v1.1 interface
- I2C slave for FM
- Two audio PCM interfaces (input and output)
- Analogue stereo (output only)
