Features  
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 10-3)  
–114 dBm (ATA8201, ASK, 2.4 Kbits/s, Manchester, BER 10-3)  
–104 dBm (ATA8202, FSK, 9.6 Kbits/s, Manchester, BER 10-3)  
–113 dBm (ATA8202, ASK, 2.4 Kbits/s, Manchester, BER 10-3)  
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  
UHF ASK/FSK  
Receiver  
Switching Between Modulation Types ASK/FSK and Different Data Rates Possible in  
1 ms Typically, Without Hardware Modification on Board to Allow Different  
Modulation Schemes  
Low Standby Current: 50 µA at 3V, 25°C  
ATA8201  
ATA8202  
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 kΩ 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 × 5 mm QFN24 Package  
Applications  
Industrial/Aftermarket Keyless Entry and Tire Pressure Monitoring Systems  
Alarm, Telemetering and Energy Metering Systems  
Remote Control Systems for Consumer and Industrial Markets  
Access Control Systems  
Home Automation  
Home Entertainment  
Toys  
4971C–INDCO–04/09
