Table 2–32. I/O Support by Bank (Part 2 of 2)
I/O Standard
Each I/O bank has its own VCCIO pins. A single device can support 1.5-,
1.8-, 2.5-, and 3.3-V interfaces; each bank can support a different standard
independently. Each bank also has dedicated VREF pins to support any
one of the voltage-referenced standards (such as SSTL-3) independently.
Each I/O bank can support multiple standards with the same V
input and output pins. Each bank can support one voltage-referenced
I/O standard. For example, when V
LVTTL, LVCMOS, 3.3-V PCI, and SSTL-3 for inputs and outputs.
Differential On-Chip Termination
Stratix devices provide differential on-chip termination (LVDS I/O
standard) to reduce reflections and maintain signal integrity. Differential
on-chip termination simplifies board design by minimizing the number
of external termination resistors required. Termination can be placed
inside the package, eliminating small stubs that can still lead to
reflections. The internal termination is designed using transistors in the
linear region of operation.
Stratix devices support internal differential termination with a nominal
resistance value of 137.5 Ω for LVDS input receiver buffers. LVPECL
signals require an external termination resistor.
