    High Speed Data level converter

    hi,

    I need to convert 0-5 V volt 50% duty cycle to +5/-5V > Data rate is 20Mbit per second. Is there any simple solution available?

    Regards

    Hi,

    The first that came into my mind: RS232 level converters. But they usually are too slow.

    Other solutions:
    * fast comparator, rail to rail push pull output, supplied with +/-5V. Input --> IN+, 2.5V --> IN-, output --> out
    * analog switch, SPDT. Input --> control, output --> COM, +5V --> NO, -5V --> NC

    Many options, e.g. SPDT analog switch, depends on required output current.

    Re: High Speed Data level converter

    Depending on how sensitive you are to things like power
    and timing symmetry and channel count, this could be a
    single "logic level" PMOSFET and a resistor load to -5V.
    But hogs power half the time and transitions would be
    pretty sensitive to loading.
