  • Melexis推出MLX72013 ASK / FSK发送器IC
    http://www.ic72.com 发布时间:2013/6/27 16:32:59


        MLX72013问/移频键控的发射机IC是专为应用程序在欧洲433 mhz工业科学医学(ISM)带,根据EN 300电信标准;但它也可以用于其他类似的标准,如村镇。FCC 15.231部分。

       
        The transmitter’s carrier frequency fc is determined by the frequency of the reference crystal fref. The integrated PLL synthesizer ensures that carrier frequencies, ranging from 425MHz to 445MHz, can be achieved. This is done by using a crystal with a reference frequency according to: fref = fc/N, where N = 16 is the PLL feedback divider ratio.

       
        Features and Benefits

       
        Fully integrated PLL-stabilized VCO Frequency range from 425 MHz to 445 MHz Single-ended RF output FSK through crystal pulling allows modulation from DC to 40 kbit/s High FSK deviation possible for wideband data transmission Wide power supply range from 1.95 V to 5.5 V Operating temperature range -40°C to +125°C Very low standby current On-chip low voltage detector High over-all frequency accuracy FSK deviation and center frequency independently adjustable Adjustable output power range from -16 dBm to +12 dBm Adjustable current consumption from 3.5 mA to 15.9 mA Conforms to EN 300 220 and similar standards
