14.2.4 Real or IQ Multiplexed
The GC5016 may be configured to have one input port for each channel. For complex data, I is followed by Q. The
Frame Strobe is set high and low, marking the start of the transmit input frame. The 1−>0 transitions of Frame Strobe
and clock transition mark time 0 (tinf_fs_dly = 0) of the input data sequence. The Real mode starts out the same as
IQ multiplexed but only the I data sample times are used.
