Transparent RF Receiver ICs for 315 MHz (ATA5746) and 433.92 MHz (ATA5745) With

High Receiving Sensitivity

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

High FSK/ASK Sensitivity:–105 dBm (ATA5746, 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

≤1 ms Typically, Without Hardware Modification on Board to Allow Different Modulation

Schemes for RKE, TPMS

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 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 +105°C

Small 5 mm × 5 mm QFN24 Package

Automotive Keyless Entry and Tire Pressure Monitoring Systems

Alarm, Telemetering and Energy Metering Systems

Supports Header and Blanking Periods of Protocols Common in RKE and TPM

Systems (Up to 52 ms in ASK Mode)

All RF Relevant Functions are Integrated. The Single-ended RF Input is Suited for Easy

Adaptation to

Allows a Low-cost Application With Only 8 Passive Components

Suitable for use in a Receiver for Joint RKE and TPMS

Optimal Bandwidth Maximizes Sensitivity while Maintaining SAW Transmitter

Compatibility

Clock Output Provides an External Microcontroller Crystal-precision Time Reference

Well Suited for Use With PLL Transmitter ATA5756/ATA5757

/ 4 or Printed-loop Antennas

–114 dBm (ATA5746, ASK, 2.4 Kbits/s, Manchester, BER 10

–104 dBm (ATA5745, FSK, 9.6 Kbits/s, Manchester, BER 10

–113 dBm (ATA5745, ASK, 2.4 Kbits/s, Manchester, BER 10
