UHF ASK/FSK Transceiver

DATASHEET

Features

● Multi channel half-duplex transceiver with approximately ±2.5MHz programmable

tuning range

● High FSK sensitivity: –106dBm at 20Kbit/s/–109.5dBm at 2.4Kbit/s (433.92MHz)

● High ASK sensitivity: –112.5dBm at 10Kbit/s/–116.5dBm at 2.4Kbit/s (433.92MHz)

● Low supply current: 10.5mA in RX and TX Mode (3V/TX with 5dBm)

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

● ASK/FSK receiver uses a low-IF architecture with high selectivity, blocking, and low

intermodulation (typical blocking 55dB at ±750kHz/61dB at ±1.5MHz and

70dB at ±10MHz, system I1dBCP = –30dBm/system IIP3 = –20dBm)

● 226kHz/237kHz IF frequency with 30dB image rejection and 170kHz usable IF

bandwidth

● Transmitter uses closed loop fractional-N synthesizer for FSK modulation with a

high PLL bandwidth and an excellent isolation between PLL/VCO and PA

● Tolerances of XTAL compensated by fractional-N synthesizer with 800Hz RF

resolution

● Integrated RX/TX-switch, single-ended RF input and output

● RSSI (Received Signal Strength Indicator)

● Communication to microcontroller with SPI interface working at max.500kBit/s

● Configurable self polling and RX/TX protocol handling with FIFO-RAM buffering of

received and transmitted data

● Five push button inputs and one wake-up input are active in power-down mode

● integrated XTAL capacitors

● PA efficiency: up to 38% (433.92MHz/10dBm/3V)

● Low in-band sensitivity change of typically ±1.8dB within ±58kHz center frequency

change in the complete temperature and supply voltage range

● Supply voltage switch, supply voltage regulator, reset generation, clock/interrupt

generation and low battery indicator for microcontroller
