AD9364 internal high TX LO with very low bandwidth

I have 40MHz external oscillator connected to XTALN pin and generating 2.67GHz Tx LO with 5MHz IF and 2.4K bandwidth with QPSK modulation, roll off of 35%.

I was not able to see proper constellation on VSA at 2.67GHz TX LO generated internally but was able to see proper constellation when used external LO.

I got proper constellation at 70MHz TX LO generated internally with same bandwidth.

Do I have to do any changes in AD9364 api to work at 2.67GHz TX LO generated internally.
