EVAL-AD7634 - External serial clock

I recently acquired an EVAL-AD7634 board and wish to operate it as stand-alone (serial slave mode), with a TI DSP TMS320F28335 as serial master. I would like to know if it's possible to provide the serial clock from the DSP to the ADC through the pin SCLK (connector P3 pin C7) . In page 3 of the related datasheet states that in this mode, SCLK (slave serial clock) = MCLK, which is a fixed clock frequency of 40MHz provided by oscillator U12.


Thanks in advance.
