The following sections provide an overview of the I/O standards supported by all Virtex-4
devices.
While most Virtex-4 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 website 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
