Features
• Multi Channel Half–duplex Transceiver with Approximately ±2.5 MHz Programmable
Tuning Range
• High FSK Sensitivity: –106 dBm at 20 kBaud/–109.5 dBm at 2.4 kBaud (433.92 MHz)
• High ASK Sensitivity: –112.5 dBm at 10 kBaud/–116.5 dBm at 2.4 kBaud (433.92 MHz)
• Low Supply Current: 10.5 mA in RX and TX Mode (3 V/TX with 5 dBm)
• Data Rate: 1 to 20 kBaud Manchester FSK, 1 to 10 kBaud Manchester ASK
• ASK/FSK Receiver Uses a Low–IF Architecture with High Selectivity, Blocking, and
Low Intermodulation (Typical Blocking 55 dB at ±750 kHz/61 dB at ±1.5 MHz and
70 dB at ±10 MHz, System I1dBCP = –30 dBm/System IIP3 = –20 dBm)
• 226 kHz IF Frequency with 30 dB Image Rejection and 170 kHz Usable IF Bandwidth
(TBD)
• Transmitter Uses Closed Loop Fractional–N Synthesizer for FSK Modulation with a
High PLL Bandwidth and an Excellent Isolation between PLL/VCO and PA
• Tolerances of XTAL Compensated by Fractional–N Synthesizer with 800 Hz RF
Resolution
• Integrated RX/TX–Switch, Single–ended RF Input and Output
• RSSI (Received Signal Strength Indicator)
• Communication to Microcontroller with SPI Interface Working at Maximum 500 kBit/s
• Configurable Self Polling and RX/TX Protocol Handling with FIFO–RAM Buffering of
Received and Transmitted Data
• 5 Push Button Inputs and One Wake–up Input are Active in Power–down Mode
• Integrated XTAL Capacitors
• PA Efficiency: up to 38% (433.92 MHz/10 dBm/3 V)
• Low In–band Sensitivity Change of Typically ±1.8 dB within ±58 kHz Center Frequency
Change in the Complete Temperature and Supply Voltage Range (TBD)
• Supply Voltage Switch, Supply Voltage Regulator, Reset Generation, Clock/Interrupt
Generation and Low Battery Indicator for Microcontroller
• Fully Integrated PLL with Low Phase Noise VCO, PLL Loop Filter and Full Support of
Multi–channel Operation with Arbitrary Channel Distance Due to Fractional–N
Synthesizer
• Sophisticated Threshold Control and Quasi–peak Detector Circuit in the Data Slicer
• Power Management via Different Operation Modes
• 315 MHz, 345 MHz, 433.92 MHz, 868.3 MHz and 915 MHz without External VCO and PLL
Components
• Inductive Supply with Voltage Regulator if Battery is Empty (AUX Mode)
• Efficient XTO Start–up Circuit (> –1.5 kΩ Worst Case Real Start–up Impedance)
• Changing of Modulation Type ASK/FSK and Data Rate without Component Changes
• Minimal External Circuitry Requirements for Complete System Solution
• Adjustable Output Power: 0 to 10 dBm Adjusted and Stabilized with External Resistor
• ESD Protection at all Pins (2 kV HBM, 200 V MM, TBD FCDM)
• Supply Voltage Range: 2.4 V to 3.6 V or 4.4 V to 6.6 V
• Temperature Range: –40°C to +85°C
• Small 7 × 7 mm QFN48 Package
