Tuning issues with ad fmcomms4 ebz with 10MHz reference clock

I am trying to configure my adfmcomms4-ebz with an external 10MHz Sine wave. The sine wave is around 1.1Vpp and I have attached my settings in the thread. I have also followed other instructions in similar forums, removed Y101 and attached C113 to the circuit. However, I obtained the following printouts:

 

SAMPL CLK: 30720000 tuning: RX
0:1:2:3:4:5:6:7:8:9:a:b:c:d:e:f:
0:# # # # # # # # # # # # # # # #
1:# # # # # # # # # # # # # # # #

ad9361_dig_tune: Tuning RX FAILED!
ad9361_init : AD936x Rev 2 successfully initialized
ad9361_validate_trx_clock_chain: Failed CMOS MODE DATA_CLK > 61.44MSPS
Done.

 

Can anyone advise me on how to interpret these printouts and change my settings so that they go away?

 

Thanks!
