I/O Assignment
3.3 V LVTTL/LVCMOS
3.3 V PCI, 3.3 V PCI-X
LVCMOS 2.5 V
LVCMOS 2.5 V / 5.0 V
LVCMOS 1.8 V
LVCMOS 1.5 V
Differential, LVDS/BLVDS/
M-LVDS/ LVPECL
Notes:
1. Can be implemented with an external IDT bus switch, resistor divider, or Zener with resistor.
2. Can be implemented with an external resistor and an internal clamp diode.
3. Bidirectional LVPECL buffers are not supported. I/Os can be configured as either input buffers or output buffers.
