FAQ

What is the maximum supported DDR3 data rate for XC6VLX195T-1FFG784C?

The XC6VLX195T-1FFG784C supports DDR3 interfaces up to 800 MHz data rate (1600 MT/s) using its hard memory controller IP. This capability is validated across all I/O banks with VCCO = 1.5V and requires board-level impedance matching to 40 Ω single-ended or 80 Ω differential traces. The XC6VLX195T-1FFG784C includes built-in write leveling and read leveling calibration logic to maintain timing margins across temperature and voltage variation.

Does XC6VLX195T-1FFG784C support PCIe Gen3?

No, XC6VLX195T-1FFG784C does not support PCIe Gen3. It integrates hard PCIe Gen2 x8 endpoint logic compliant with PCI Express Base Specification Revision 2.0. The GTX transceivers operate up to 6.6 Gb/s, which meets Gen2 requirements (5.0 GT/s) but falls short of Gen3's 8.0 GT/s minimum. For PCIe Gen3 designs, engineers must consider Virtex-7 or newer families such as the XC6VLX195T-1FFG784C's successor devices.

What is the operating temperature range for XC6VLX195T-1FFG784C?

The XC6VLX195T-1FFG784C is rated for commercial (0°C to 85°C) and industrial (-40°C to 100°C) temperature ranges, with the "C" suffix indicating commercial grade. Its FFG784 package is qualified to JEDEC JESD22-A104 reliability standards for 1000 cycles of temperature cycling. The XC6VLX195T-1FFG784C maintains timing closure across this range using on-die temperature sensors and adaptive voltage scaling in the MMCM.

How many GTX transceivers are available on XC6VLX195T-1FFG784C?

The XC6VLX195T-1FFG784C contains 24 GTX transceiver quads, each supporting data rates from 600 Mb/s to 6.6 Gb/s. These transceivers are grouped into four banks (GTX0–GTX3), with six quads per bank. Each quad includes dedicated TX/RX phase alignment circuits and shared reference clock inputs. The XC6VLX195T-1FFG784C supports protocols including CPRI, SATA II, and PCIe Gen2 without external retimers.

Is XC6VLX195T-1FFG784C pin-compatible with other Virtex-6 devices?

XC6VLX195T-1FFG784C is not pin-compatible with other Virtex-6 devices due to unique ball mapping optimized for its 195K logic cell count and I/O bank distribution. While it shares the FFG784 package outline with smaller Virtex-6 variants like XC6VLX75T, the power, configuration, and transceiver pin assignments differ significantly. Migration to XC6VLX195T-1FFG784C requires full PCB redesign and signal integrity validation.
