Frequently Asked Questions (FAQ)
What does the “L2” speed grade mean in XC7VX980T-L2FFG1926E?
The “L” prefix in the speed grade designation indicates a low-power variant. The -L2 grade is optimized for reduced static power consumption versus the standard commercial -2 grade, while maintaining the same performance characteristics. This makes it suitable for applications where thermal management is a design constraint.
What is the maximum transceiver data rate for XC7VX980T-L2FFG1926E?
The GTX transceivers in the XC7VX980T support data rates from 600 Mb/s up to 11.3 Gb/s per lane, with a special low-power mode available for chip-to-chip interfaces.
Is the XC7VX980T-L2FFG1926E suitable for industrial and defense applications?
Yes. The “E” temperature suffix confirms an extended temperature range of –40°C to +100°C, making it suitable for industrial, defense, and aerospace deployments where commercial-grade temperature ratings are insufficient.
How many user I/Os does the XC7VX980T-L2FFG1926E have?
The FFG1926 package configuration provides 720 user I/O pins. If your design requires more I/Os, the FFG1930 package variant of the same device offers 900 user I/Os.
