Virtex-7 T and XT FPGAs Data Sheet:
DC and Switching Characteristics
DS183 (v1.11) January 31, 2013
Preliminary Product Specification
Introduction
Virtex®-7 T and XT FPGAs are available in -3, -2, -1, and
-2L speed grades, with -3 having the highest performance.
grade (that is, the timing characteristics of a -1 speed grade
industrial device are the same as for a -1 speed grade
commercial device). However, only selected speed grades
and/or devices are available in each temperature range.
The -2L devices operate at V
= 1.0V and are screened
CCINT
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.
All supply voltage and junction temperature specifications
are representative of worst-case conditions. The
parameters included are common to popular designs and
typical applications.
This Virtex-7 Tand XT FPGA data sheet, part of an overall
set of documentation on the 7 series FPGAs, is available on
the Xilinx website at www.xilinx.com/7.
Virtex-7 Tand XT FPGA DC and AC characteristics are
specified in commercial, extended, and industrial
temperature ranges. Except the operating temperature
range or unless otherwise noted, all the DC and AC
electrical parameters are the same for a particular speed
All specifications are subject to change without notice.
