FM Radio & Bluetooth
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
