Top Features of the XC7VX690T-L2FFG1930E
Advanced 6-Input LUT Architecture
The device uses real 6-input Look-Up Tables (LUT6) configurable as distributed memory, enabling compact, high-speed logic implementations that reduce routing overhead compared to older 4-LUT architectures.
High-Speed GTX Transceivers
With 80 GTX transceivers capable of operating from 600 Mb/s up to 11.3 Gb/s, the XC7VX690T-L2FFG1930E can handle demanding serial protocols including PCIe, 10G/40G/100G Ethernet, Interlaken, OTN, and CPRI/OBSAI in wireless backhaul applications.
Integrated PCIe Interface Block
The device includes a hardened PCIe Gen 3 x8 interface block, reducing resource utilization and design complexity when interfacing with host CPUs and SSD controllers.
XADC Analog Interface
An on-chip Xilinx Analog-to-Digital Converter (XADC) provides dual 12-bit, 1 MSPS ADC channels with integrated thermal and voltage supply sensors — enabling real-time system health monitoring without external components.
Low-Power “L2” Operation
The “L2” speed grade is engineered to deliver the same switching performance as a standard -2 device while consuming significantly less static and dynamic power — a key advantage in deployments where thermal management and power budgets are tightly constrained.

Frequently Asked Questions
Q: What is the difference between the XC7VX690T-L2FFG1930E and XC7VX690T-2FFG1930C? The L2 variant is a low-power version of the -2 speed grade intended for extended temperature range applications (0°C to +100°C). The -2C is a standard commercial grade device rated 0°C to +85°C. They share the same die and package but differ in validated operating conditions and power profiles.
Q: Is the XC7VX690T-L2FFG1930E pin-compatible with the XC7VX690T-2FFG1930C? Yes — both use the FFG1930 package, making them footprint-compatible for PCB design reuse.
Q: What transceiver protocols are natively supported? The GTX transceivers support PCIe Gen 3, 10GbE, CPRI, OTN (OTU2/OTU3), SATA/SAS, and custom serial protocols. Soft IP cores from AMD’s IP catalog expand support further.
Q: Which Vivado version should I use? AMD recommends using Vivado 2018.3 or later for best device support and IP compatibility with the Virtex-7 family.
Summary
The XC7VX690T-L2FFG1930E offers an exceptional balance of logic density, transceiver performance, DSP throughput, and power efficiency within the Virtex-7 XT family. Its 693,120 logic cells, 80 GTX transceivers (up to 11.3 Gb/s), 3,600 DSP slices, and 52,920 Kbits of block RAM make it one of the most capable mid-to-high-density FPGAs available in the 28nm generation.
