1 / 42 page  9249C-RKE-10/14 Features ● Transparent RF receiver ICs for 315MHz (Atmel® ATA5746C) and 433.92MHz (Atmel ATA5745C) with high receiving sensitivity ● Fully integrated PLL with low phase noise VCO, PLL, and loop filter ● High FSK/ASK sensitivity: ● –105dBm (Atmel ATA5746C, FSK, 9.6Kbits/s, Manchester, BER 10-3) ● –114dBm (Atmel ATA5746C, ASK, 2.4Kbits/s, Manchester, BER 10-3) ● –104dBm (Atmel ATA5745C, FSK, 9.6Kbits/s, Manchester, BER 10-3) ● –113dBm (Atmel ATA5745C, ASK, 2.4Kbits/s, Manchester, BER 10-3) ● Supply current: 6.5mA in Active Mode (3V, 25°C, ASK Mode) ● Data rate: 1Kbit/s to 10Kbits/s Manchester ASK, 1Kbit/s to 20Kbits/s Manchester FSK with four programmable bit rate ranges ● Switching between modulation types ASK/FSK and different data rates possible in ≤ 1ms typically, without hardware modification on board to allow different modulation schemes for RKE, TPMS ● Low standby current: 50µA at 3V, 25°C ● ASK/FSK receiver uses a Low-IF architecture with high selectivity, blocking, and Low intermodulation (typical 3-dB blocking 68.0dBC at ±3MHz/74.0dBC at ±20.0MHz, system I1dBCP = –31dBm/system IIP3 = –24dBm) ● Telegram pause up to 52ms 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 65dB ● Low in-band sensitivity change of typically ±2.0dB 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 (> –1.4k Ω worst-case start impedance) ● Clock generation for microcontroller ATA5745C/ATA5746C UHF ASK/FSK Receiver DATASHEET |
