The output interface of the ADS528x is normally a DDR interface, with the LCLK rising edge and falling edge

transitions in the middle of alternate data windows. This default phase is shown in Figure 1.

Figure 1. Default Phase of LCLK

The phase of LCLK can be programmed relative to the output frame clock and data using bits

PHASE_DDR<1:0>. The LCLK phase modes are shown in Figure 2.
