The LVDS drive strength of the bit clock (LCLKP or LCLKM) and the frame clock (FCLKP or FCLKM) can be

individually programmed. The LVDS drive strengths of all the data outputs OUTP and OUTM can also be

programmed to the same value.

All three drive strengths (bit clock, frame clock, and data) are programmed using sets of three bits. Table 15

shows an example of how the drive strength of the bit clock is programmed (the method is similar for the frame

clock and data drive strengths).
