FAQ

What is the maximum data rate supported by the GTX transceivers in XC6VLX550T-2FFG1759C?

The GTX transceivers in XC6VLX550T-2FFG1759C support a maximum data rate of 6.6 Gb/s per lane. This enables compliance with PCIe Gen2, SRIO v2, and SATA II protocols. The transceiver architecture includes built-in clock data recovery, pre-emphasis, and receiver equalization to maintain signal integrity at this rate. XC6VLX550T-2FFG1759C achieves this performance within specified temperature and voltage ranges defined in the official Virtex-6 DC and switching characteristics documentation.

Does XC6VLX550T-2FFG1759C support partial reconfiguration?

Yes, XC6VLX550T-2FFG1759C supports partial reconfiguration through its FPGA fabric and configuration logic. This capability allows dynamic replacement of specific logic modules without resetting the entire device or interrupting active functions. Implementation requires use of Xilinx ISE Design Suite 14.7 or later with appropriate constraints and bitstream generation flow. XC6VLX550T-2FFG1759C leverages frame-based configuration memory access to enable secure, verified module swaps during runtime.

What I/O standards are supported by XC6VLX550T-2FFG1759C?

XC6VLX550T-2FFG1759C supports LVDS, Mini-LVDS, RSDS, BLVDS, SSTL, HSTL, and TMDS across its 24 configurable I/O banks. Each bank operates independently with selectable VCCO voltages from 1.2 V to 3.3 V. Differential standards support internal termination and programmable drive strength. XC6VLX550T-2FFG1759C does not support current-mode logic (CML) or PECL natively without external level-shifting circuitry.

What is the core voltage requirement for XC6VLX550T-2FFG1759C?

XC6VLX550T-2FFG1759C requires a nominal core supply voltage of 1.0 V with a tolerance of ±3%, as specified in the Virtex-6 DC and switching characteristics datasheet. This voltage must be delivered with low noise and tight regulation, especially under dynamic switching loads. XC6VLX550T-2FFG1759C includes dedicated VCCINT monitoring circuitry to trigger brown-out protection if voltage falls outside operational range.

Is XC6VLX550T-2FFG1759C still in active production?

XC6VLX550T-2FFG1759C is in long-term availability status with AMD/Xilinx, supported under the Virtex-6 product discontinuance notice (PDN) program. While no longer in high-volume production, it remains available through authorized distributors and Aetrix Electronics with controlled-lifecycle sourcing. XC6VLX550T-2FFG1759C continues to be qualified for aerospace and defense applications with extended temperature screening options.
