Virtex-4 FPGA Electrical Characteristics
Virtex®-4 FPGAs are available in -12, -11, and -10 speed
grades, with -12 having the highest performance.
Virtex-4 FPGA DC and AC characteristics are specified for
both commercial and industrial grades. Except the operating temperature range or unless otherwise noted, all the DC
and AC electrical parameters are the same for a particular
speed grade (that is, the timing characteristics of a -10
speed grade industrial device are the same as for a -10
speed grade commercial device). However, only selected
speed grades and/or devices might be available in the
industrial range.
All supply voltage and junction temperature specifications
are representative of worst-case conditions. The parameters included are common to popular designs and typical
applications.
