21 / 341 page ![]() Chapter 1: Stratix III Device Datasheet: DC and Switching Characteristics 1–11 Electrical Characteristics © July 2010 Altera Corporation Stratix III Device Handbook, Volume 2 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). VCC_CLKIN is the power supply for the differential column clock input pins. VCCPD is the power supply for the row I/Os and all other column I/Os.

OCT or lower current strengths may provide better signal integrity and lower power. Table 1–15.
