Virtex-7TandXT FPGAs Data Sheet:
DC and AC Switching Characteristics
DS183 (v1.28) March 13, 2019Product Specification
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 12.5Gb/s GTX or 13.1Gb/s GTH transceivers as
well as the standard -2 speed grade specifications.
Virtex-7TandXT 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.
