(1)

For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.

(2)

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.

(3)

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.

(4)

To pull up a signal to the opposite supply rail, a 1 k

Ω resistor is recommended.

(5)

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.
