LVTTL (Low Voltage Transistor-Transistor Logic)
The following subsections provide an overview of the I/O standards supported by all
Virtex-5 devices.
While most Virtex-5 FPGA I/O supported standards specify a range of allowed voltages,
this chapter records typical voltage values only. Detailed information on each specification
can be found on the Electronic Industry Alliance JEDEC web site at
The low-voltage TTL (LVTTL) standard is a general purpose EIA/JESDSA standard for
3.3V applications using an LVTTL input buffer and a push-pull output buffer. This
standard requires a 3.3V input and output supply voltage (V
use of a reference voltage (V
