FSK RF/FSK RF Transceiver/Wireless Transceiver-RFM12

DESCRIPTION : RFM12 is a low costing ISM band transceiver module implemented with unique PLL. It works signal ranges from 315/433/868/915MHZ bands, comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. Features: low costing, high performance and price ratio tuning free during production PLL and zero IF technology fast PLL lock time high resolution PLL with 2.5KHz step high data rate (up to 115.2 kbps with internal demodulator) differential antenna input automatic antenna tuning Programmable TX frequency deviation (15 to 240 KHz) programmable receiver bandwidth (67 - 400 kHz) analog and digital signal strength indicater(ARSSI/DRSSI) AFC DQD Internal data filtering and clock recovery RX synchron pattern recognition SPI interface clock and reset signal output for external MCU use 16 bit RX Data FIFO Two 8 bit TX data registers 10MHz crystal for PLL timing wakeup timer 2.2V - 5.4V power supply low power consumption stand by current less than 0.3µA Typical Application Remote control Remote sensor Wireless data collection Home security system Toys Tire pressure monitoring system
