    How we select LC filter for MAX3221?

    I have seen a schematic where they used MAX3221, RS232 Driver and Receiver. There they have used LC filter of inductor value 0.68uH and capacitor value of 680pF, but in datasheet they have not mentioned about frequency. Can anyone explain how they selected this value?
