Notes:
1. Device powered and unconfigured.
2. Currents for conditions other than values specified in this table can be obtained by using the XPOWER Estimator (XPE) or XPOWER Analyzer (XPA)
tools.
3. GTP transceiver quiescent supply current for an entire device can be calculated by multiplying the values in this table by the number of available GTP
transceivers.
4. Does not include power-up MGTAVTTRCAL supply current during device configuration.
5. Typical values are specified at nominal voltage, 25°C.
GTP Transceiver DC Input and Output Levels
Table 16 summarizes the DC output specifications of the GTP transceivers in Spartan-6 FPGAs. Figure 1 shows the single-
ended output voltage swing. Figure 2 shows the peak-to-peak differential output voltage.
Consult UG386: Spartan-6 FPGA GTP Transceivers User Guide for further details.

Notes:
1. The output swing and preemphasis levels are programmable using the attributes discussed in the Spartan-6 FPGA GTP Transceivers User Guide
and can result in values lower than reported in this table.
2. Other values can be used as appropriate to conform to specific protocols and standards.
