    Minseong,

              150 MHz is the operational frequency of this device so it is no surprise you see emissions in that frequency.

    1. Is the XCLKOUT pin toggling at 150 MHz? If so, you could turn off the signal.
    2. Have you tried affixing a flexible EMI suppressor on top of the device? This could possibly tell you if the source of the emission is the device itself or traces connected to the DSP.
    3. Would you be willing to share the schematics and layout offline with me? You can do this by initiating a friendship request with me. Simply hover the cursor over my name and initiate the request.
