Notes:
1. Typical values are specified at nominal voltage, 25°C.
2. Device powered and unconfigured.
3. Currents for conditions other than values specified in this table can be obtained by using the XPOWER Estimator (XPE) or XPOWER
Analyzer (XPA) tools.
4. GTX_DUAL tile quiescent supply current for an entire device can be calculated by multiplying the values in this table by the number of
available GTX_DUAL tiles in the target TXT or FXT device.
GTX_DUAL Tile DC Input and Output Levels
Table 40 summarizes the DC output specifications of the GTX_DUAL tiles in Virtex-5 FPGAs. Figure 6 shows the single-
ended output voltage swing. Figure 7 shows the peak-to-peak differential output voltage.
Consult UG198:Virtex-5 FPGA RocketIO GTX Transceiver User Guide for further details.

Notes:
1. The output swing and preemphasis levels are programmable using the attributes discussed in UG198:Virtex-5 FPGA RocketIO GTX
Transceiver User Guide and can result in values lower than reported in this table.
2. Values outside of this range can be used as appropriate to conform to specific protocols and standards.
