Product Brief 55mm 4&.5&$)"%7"/$&%$0..6/*$"5*0/44&/4*/( Pin1 SM1223 - E433/868/915 30mm 433, 868 and 915 MHz RF Transmitter Evaluation Module General Description: Key Product Features: The SM1223s are complete Radio Transmitter Modules operating either in the 433 or 868 or 915 MHz license free ISM (Industrial Scientific and Medical) frequency bands. Based on the SX1223 Transmitter, the SM1223 radio module is suitable for applications seeking to satisfy the European (ETSI EN300-220-1and EN301 439-3) or the North American (FCC part 15.247 and 15.249) regulatory standards. • No RF knowledge required • Direct digital interface • Fully assembled and tested • Easy connection using connectors • Optimized low cost design 2 layers PC-Board Small footprint – 15 mm x 20 mm • Supply voltage 2.2 V – 3.6 V • Fully integrated VCO and frequency synthesizer • Output power is programmable up to 10 dBm • Data rate up to 153.6 kbit/s • Current consumption Tx = 25.8 mA at 10 dBm SX1223 is a single chip transmitter highly integrated architecture allows for minimum external components while maintaining design flexibility. All major RF communication parameters are programmable and most of them can be set dynamically. The SX1223 offers the advantage of high data rate communication at rates of up to 153.6 kbit/s. The SX1223 is optimized for low cost applications while offering high RF output power. The device is suitable for applications which have to satisfy either the European (ETSI-300-220) or the North American (FCC part 15) Regulatory standards. Applications: • Active RFID • Wireles remote control • Automated Meter Reading (AMR) • Home automation and access control • High-quality speech, music and data over RF W W W .SE MTE C H .C OM Product Brief SM1223- 433, 868 and 915 MHz RF Transmitter Evaluation Module Symbol Parameter Condition Min Typ Max Unit SM1223C433T SM1223C868T SM1223C915T 433 868 902 - 435 870 928 MHz - 0.2 1 μA - 0.2 0.3 mA 6 FR Synthesizer frequency range IDDSL Sleep mode supply current IDDST Standby mode supply current 16 MHz running IDDFS Supply current in FS Mode 16 MHz running 4.2 PRF = 0 dBm 12 IDDT TX mode supply current FDA Frequency deviation BR Bit rate RFOP Max RF output power PRF = 10 dBm (2) TS_STR Transmitter wake-up time TS_OS Quartz oscillator wake up time mA 25 mA 255 (1) kHz 19.2 Kb/s Programmable 5 Programmable 1.2 Programmable (3 dB step) 8 10 From oscillator enabled - 250 500 Fundamental - 1 2 4.8 dBm 16 μs ms MHz XTAL Quartz oscillator frequency PHN Phase noise -79 - dBc/Hz VIH Digital input level high % VDD 75 - - % VIL Digital input level low % VDD - - 25 % 10dBm unmodulated (50 kHz from carrier) (1): 250 kHZ max at 433 MHz band (2): Loop filter would have to be optimized to guaranty performances at other than typical bit rate and center frequency.
