Note to Table 1–15:
(1) Use the current strength settings that are equal or larger than the I_OL and I_OH values listed to meet the V_OL and V_OH specifications for each line.
OCT or lower current strengths may provide better signal integrity and lower power.
Refer to the figures for “Differential I/O Standards” in “Glossary” on page 1–326 for
the receiver input and transmitter output waveforms, and for all the differential I/O
standards (LVDS, mini-LVDS, RSDS). V_{CC_CLKIN} is the power supply for the differential
column clock input pins. V_CCPD is the power supply for the row I/Os and all other
column I/Os.
