Introduction
Virtex®-7 T and XT FPGAs are available in -3, -2, -1, and
-2L speed grades, with -3 having the highest performance.
The -2L devices operate at V
CCINT
= 1.0V and are screened
for lower maximum static power. The speed specification of
a -2L device is the same as the -2 speed grade. The -2G
speed grade is available in devices utilizing Stacked Silicon
Interconnect (SSI) technology. The -2G speed grade
supports 12.5 Gb/s GTX or 13.1 Gb/s GTH transceivers as
well as the standard -2 speed grade specifications.
Virtex-7 T and XT FPGA DC and AC characteristics are
specified in commercial, extended, industrial, and military
temperature ranges. Except for 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 -1M speed
grade military device are the same as for a -1C speed grade
commercial device). However, only selected speed grades
and/or devices are available in each temperature 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.
