FAQ

What is the maximum operating frequency of the XC5VLX155T-2FFG1738C?

The XC5VLX155T-2FFG1738C is rated at speed grade -2, guaranteeing reliable operation up to 500 MHz for system clocks and 3.75 Gb/s for GTP transceivers under worst-case voltage and temperature conditions. Actual achievable frequency depends on design placement, routing, and I/O standard selection, but the -2 grade ensures timing closure for demanding high-speed interfaces like PCIe Gen1 and DDR2-533.

Does the XC5VLX155T-2FFG1738C support JTAG boundary-scan testing?

Yes, the XC5VLX155T-2FFG1738C fully supports IEEE 1149.1 JTAG boundary-scan for board-level test and debug. Its TAP controller enables instruction register access, device identification, and boundary-scan register read/write operations. This capability is used during manufacturing test and in-system verification of I/O connectivity and solder joint integrity on PCBs using the XC5VLX155T-2FFG1738C.

What configuration modes are supported by the XC5VLX155T-2FFG1738C?

The XC5VLX155T-2FFG1738C supports multiple configuration modes including Master SelectMAP, Slave SelectMAP, JTAG, and Serial PROM. Mode selection is controlled by M0–M2 pins at power-up. Each mode defines how the bitstream is loaded-via parallel bus, external SPI flash, or JTAG interface-and determines whether configuration is initiated automatically or triggered externally.

Is the XC5VLX155T-2FFG1738C compatible with Xilinx ISE Design Suite 14.7?

Yes, the XC5VLX155T-2FFG1738C is fully supported in Xilinx ISE Design Suite 14.7, including synthesis, place-and-route, timing analysis, and bitstream generation. This version remains the final official tool release for Virtex-5 devices, and all device-specific primitives, constraints, and simulation models are validated for use with XC5VLX155T-2FFG1738C in this environment.

What thermal management considerations apply to the XC5VLX155T-2FFG1738C?

The XC5VLX155T-2FFG1738C has a thermal resistance of θ_JA = 3.5°C/W and θ_JB = 1.8°C/W under JEDEC standards. Effective thermal management requires a 6-layer PCB with internal ground/power planes, thermal vias under the package, and a heatsink rated for ≥15 W dissipation. Junction temperature must remain below 100°C during operation to ensure reliability and timing stability of the XC5VLX155T-2FFG1738C.
