XC7VX690T-2FFG1761C Detailed Technical Features

## Logic Fabric and Configurable Logic Blocks (CLBs)

The XC7VX690T-2FFG1761C is built around an advanced 6-input Look-Up Table (LUT) architecture. Each LUT can be configured as logic or as distributed RAM, providing designers maximum flexibility. With 108,300 CLBs and 693,120 logic cells, this FPGA handles complex multi-million gate designs with ease.

## Block RAM and On-Chip Memory

On-chip memory is a critical resource for data-intensive FPGA designs. The XC7VX690T-2FFG1761C provides:

The 36Kb dual-port block RAM modules include built-in FIFO logic, making them ideal for on-chip data buffering, streaming pipelines, and high-throughput memory interfaces.

## DSP Slices and Signal Processing Performance

The Virtex-7 XT family delivers exceptional DSP capability. The XC7VX690T supports up to 4.7 TMAC/s DSP throughput at the family level, making it a strong fit for:

• Software-Defined Radio (SDR)
• Medical imaging signal processing
• Financial analytics acceleration
• Radar and electronic warfare

## High-Speed Serial Transceivers (GTH/GTX)

One of the defining features of the XC7VX690T-2FFG1761C is its high-speed serial connectivity:

## SelectIO Technology and DDR Support

The 850 user I/Os leverage Xilinx SelectIO technology with support for DDR3 interfaces at up to 1,866 Mb/s, enabling high-bandwidth connections to external memory and high-speed peripherals.

## Clock Management (CMT)

Precise, low-jitter clock distribution is critical in high-speed FPGA designs. The XC7VX690T-2FFG1761C features Clock Management Tiles (CMTs) that include:

• Phase-Locked Loops (PLLs)
• Mixed-Mode Clock Managers (MMCMs)

These enable flexible, low-jitter clock synthesis and management for complex multi-clock-domain designs.

## XADC – User-Configurable Analog Interface

The integrated XADC block includes:

This makes the XC7VX690T-2FFG1761C particularly useful in system-level monitoring applications where real-time temperature and power measurement is required.
