2. Pin Description
NOTES:
1.
Dedicated differential input buffers can receive both LVDS and LVPECL voltage levels using
3.3V supply.
2.
V
DD
.PAD is 2.5V for LVDS outputs or 3.3V for LVPECL outputs.
Dedicated differential output buffers can be biased using different supplies for V
DD
.PAD and
external resistors to support both LVDS and LVPECL output voltage levels.
3.
4.
The LVTTL control, JTAG pins, and differential input ports are 3.3V
they are not 5V tolerant.
5.
The differential output pins powered from 2.5V are 3.3V tolerant.
