FAQ

What is the maximum supported data rate for GTP transceivers on the XC5VLX155T-2FFG1136I?

The XC5VLX155T-2FFG1136I integrates 24 GTP transceivers each rated for up to 3.75 Gbps. This supports protocols including SATA Gen2 (3 Gbps), Serial RapidIO 1.2 (3.125 Gbps), and CPRI v4.1 (up to 3.072 Gbps). Performance is guaranteed at -2 speed grade under industrial temperature conditions.

Does the XC5VLX155T-2FFG1136I support partial reconfiguration?

Yes, the XC5VLX155T-2FFG1136I supports partial reconfiguration through its hierarchical design flow and dedicated configuration logic. This allows dynamic swapping of functional modules-such as filter banks or modulation schemes-without resetting the entire FPGA fabric or halting system operation.

What I/O standards are supported by the XC5VLX155T-2FFG1136I?

The XC5VLX155T-2FFG1136I supports 18 I/O standards via SelectIO technology, including LVDS, SSTL-18/2, HSTL Class I/II, PCI-X, and differential HSTL. Each of its 640 user I/Os is configurable per-bank with independent VCCO voltages ranging from 1.2 V to 3.3 V.

What is the purpose of the VCCAUX supply on the XC5VLX155T-2FFG1136I?

The VCCAUX supply (2.5 V ±5%) powers the XC5VLX155T-2FFG1136I's configuration logic, clock management tiles (CMT), and GTP transceiver analog circuitry. Stable VCCAUX is required for reliable bitstream loading, clock synthesis, and transceiver calibration sequences during startup and operation.

Is the XC5VLX155T-2FFG1136I qualified for industrial temperature operation?

Yes, the XC5VLX155T-2FFG1136I is specified for industrial temperature range (-40°C to +100°C) and carries the 'I' suffix designation. Thermal design must account for 15 W typical power dissipation in the FFG1136 package, with attention to PCB copper pour and airflow in enclosed environments.
