    Hello,
    As the subject states, I am sending a signal via standard 38khz
    modulated IR. Is there any 1 chip solutions to this?
    Thanks,
    BB

    Of course; a PIC with built-in hardware PWM (such as the 16F628) if by
    one chip you meant a single chip for generating the data signal as
    well as the 38 KHz carrier. If you meant just generating the carrier,
    a simple 555 would do as well.
