Applications

•

Transparent RF Receiver ICs for 315 MHz (ATA8201) and 433.92 MHz (ATA8202) With

High Receiving Sensitivity

Fully Integrated PLL With Low Phase Noise VCO, PLL, and Loop Filter

High FSK/ASK Sensitivity:–105 dBm (ATA8201, FSK, 9.6 Kbits/s, Manchester, BER 10

Supply Current: 6.5 mA in Active Mode (3V, 25°C, ASK Mode)

Data Rate: 1 Kbit/s to 10 Kbits/s Manchester ASK, 1 Kbit/s to 20 Kbits/s Manchester

FSK With Four Programmable Bit Rate Ranges

Switching Between Modulation Types ASK/FSK and Different Data Rates Possible in

Modulation Schemes

Low Standby Current: 50 µA at 3V, 25°C

ASK/FSK Receiver Uses a Low-IF Architecture With High Selectivity, Blocking, and

Low Intermodulation (Typical 3-dB Blocking 68.0 dBC at ±3 MHz/74.0 dBC at

±20.0 MHz, System I1dBCP = –31 dBm/System IIP3 = –24 dBm)

Telegram Pause Up to 52 ms Supported in ASK Mode

Wide Bandwidth AGC to Handle Large Out-of-band Blockers above the System I1dBCP

440-kHz IF Frequency With 30-dB Image Rejection and 420-kHz IF Bandwidth to

Support PLL Transmitters With Standard Crystals or SAW-based Transmitters

RSSI (Received Signal Strength Indicator) With Output Signal Dynamic Range of 65 dB

Low In-band Sensitivity Change of Typically ±2.0 dB Within ±160-kHz Center

Frequency Change in the Complete Temperature and Supply Voltage Range

Sophisticated Threshold Control and Quasi-peak Detector Circuit in the Data Slicer

Fast and Stable XTO Start-up Circuit (> –1.4 k Worst-case Start Impedance)

Clock Generation for Microcontroller

ESD Protection at all Pins (±4 kV HBM, ±200V MM, ±500V FCDM)

Dual Supply Voltage Range: 2.7V to 3.3V or 4.5V to 5.5V

Temperature Range: –40°C to +85°C

Small 5 mm

Industrial/Aftermarket Keyless Entry and Tire Pressure Monitoring Systems

Alarm, Telemetering and Energy Metering Systems

Remote Conrol Systems for Consumer and Industrial Markets

Access Control Systems
