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

Transmitter Uses Closed Loop Fractional-N Synthesizer for FSK Modulation with a

High PLL Bandwidth and an Excellent Isolation between PLL 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 MHz/10 dBm/3 V)

Low Inband Sensitivity Change of Typically ±1.8 dB within ±58 kHz Center Frequency

Change in the Complete Temperature and Supply Voltage Range

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 and PLL Loop Filter

Sophisticated Threshold Control and Quasi Peak Detector Circuit in the Data Slicer

Power Management via Different Operation Modes

433.92 MHz, 868.3 MHz and 315 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 k Worst Case Start 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)

Supply Voltage Range: 2.4 V to 3.6 V or 4.4 V to 6.6 V

Temperature Range: -40°C to +105°C

Small 7

Automotive Keyless Entry and Passive Entry Go Systems

Access Control Systems

Remote Control Systems

Alarm and Telemetry Systems

Energy Metering

Home Automation

No SAW Device Needed in Key Fob Designs to Meet Automotive Specifications

Low System Cost Due to Very High System Integration Level

Only One Crystal Needed in System

Less Demanding Specification for the Microcontroller Due to Handling of Power-down

Mode, Delivering of Clock, Reset, Low Battery Indication and Complete Handling of

Receive/Transmit Protocol and Polling

Single-ended Design with High Isolation of PLL/VCO from PA and the Power Supply

Allows a Loop Antenna in the Key Fob to Surround the Whole Application
