Different response across two channels in same adrv9009

Category: Software
Product Number: ADRV9009
Software Version: Linux 14.04

I am transmitting same 100M OFDM data across two channels of the ADRV9009.But for one of the channel  I am seeing the response in 491.52MHz which is wrong ,because I am transmitting the 100MHz bandwidth signal.One of the channel its correct.

Is it anything to do with the  below parameter ?

adi,jesd204-deframer-a-deserializer-lane-crossbar = <0xC6>;

I am attaching the frequency response plots for the better understanding.

can anyone help me with this .what I am missing ?
