For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.
These I/O specifications apply to regular 3.3 V I/Os and do not apply to DDR2/mDDR, USB I/Os. DDR2/mDDR I/Os are 1.8 V I/Os and
adhere to JESD79-2A standard, USB I/Os adhere to USB2.0 spec.
This specification applies only to pins with an internal pullup (PU) or pulldown (PD). See
Section 2.4
or
Section 2.5
for pin descriptions.
To pull up a signal to the opposite supply rail, a 1 k
resistor is recommended.
100% color bars are not supported. 100% color bars require 1.2 V peak-to-peak. The video buffer only provides 1.0 V peak-to-peak.
