Features

• 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^-3)

–114 dBm (ATA5746, ASK, 2.4 Kbits/s, Manchester, BER 10^-3)

–104 dBm (ATA5745, FSK, 9.6 Kbits/s, Manchester, BER 10^-3)

–113 dBm (ATA5745, 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 for RKE, TPMS

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

ATA5745

ATA5746

• 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 kΩWorst-case Start Impedance)

• Clock Generation for Microcontroller

Preliminary

• 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

Applications

• Automotive Keyless Entry and Tire Pressure Monitoring Systems

• Alarm, Telemetering and Energy Metering Systems

Benefits

• 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 λ / 4 or Printed-loop Antennas

• 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
