Features
• Single chip IC with 2.4 GHz transceiver and GFSK modem with digital interface to external baseband processor. • Fully compliant with Bluetooth specification 1.1 and 1.2. • Supports multiple external reference clocks or crystal frequencies with onchip reference PLL. • Direct-conversion architecture with no external channel filter or VCO resonator components. • Single-ended RX/TX pins reduce system BOM cost by eliminating a balun. On-chip RX/TX switching eliminates external RX/TX switch. • Typical -85 dBm receiver sensitivity with excellent interference rejection performance. • Class 2 and 3 transmit output power up to +4 dBm with output power control loop for accurate power control. • Hardware AGC dynamically adjusts receiver performance in changing environments. • Low out-of-band spurious emissions prevents interference with mobile phone frequencies. • Option for Class 1 designs with RX/TX switch control and multiple modes of gain control. • On-chip voltage regulation simplifies voltage input requirement. Regulator bypass mode enables use of external regulator. • 1.8 Volt analog and digital core voltages; 1.63 Volt to 3.63 Volt external I/O interface voltage. • Low power consumption in active and standby modes.
