TMS320C6655: Noise on the McBSP1 transmitter pins: DX and FSX

Hello TI experts,

I configured the transmitter of McBSP1 on C6655 as follows:

• 1 phase
• 1 element in phase 1
• The size of the element is 16-bit
• The internal clock is used to generate the clock and frame sync signals.

I used the oscilloscope to measure the DX and FSX pins. Please see the below image. (CH1 is the frame sync, Ch2 is the data:0xA5A5)

Are these signals acceptable? Is there any solution to reduce the overshoot?

Thanks.
