Pin Description
The differential output pins powered from 2.5V are 3.3V tolerant.
Note 1: Dedicated differential input buffers can receive both LVDS and LVPECL voltage levels using 3.3V supply.
Note 2: V
Note 3: The LVTTL control, JTAG pins, and differential input ports are 3.3V—they are not 5V tolerant.
