AD9364 (FMCOMMS4) 122.88 Ms/s rate

I would like put out I/Q samples at the 122.88 Ms/s rate. My set up is a zedboard with a FMCOMMS4. According to the UG 673 reference manual, Table 53, 122.88 MSPS is the maximum rate using LVDS. When I attempt to program a 122.88 MSPS rate using the API, it throws an error and defaults to 61.44. Is 122.88 complex MSPS possible? Is the table referring to the complex sampling rate or to the rate over the bus (61.44 I and 61.44 Q)? Is the 122.88 MSPS in Table 53 referring to a 61.44 Ms/s complex sampling?

Thanks
