I can give the answer to myself ;-) Took a while ...

So, data is transferred on the falling and rising edge of master strobe 
(which is not connected to the FPGA). The half period of MSTB is 1 IFCLK 
cycle (which is the minimum). Hence, data is actually transferred once 
per IFCLK cycle (twice per MSTB cycle). MSTB is toggling at 24 Mhz. This 
gives a data rate of 96 Mb/s (16 bit per IFCLK cycle, which runs at 48 Mhz).

IFCLK is generated internally, and output inverted to the FPGA.
