CPRI operation is largely defined in units of the “chip period,” defined in the 3GPP specifications as T C = 1/3.84 MHz; or 260.416667 ns. In particular, the CPRI basic frame length is defined as 1 T C , so all in-phase and quadrature-phase data (I/Q) data and frame synchronization depend directly on this time constant.
