RocketIO DC Input and Output Levels
Table 12 summarizes the DC input and output specifica-
tions of the Virtex-4 FPGA RocketIO Multi-Gigabit Serial
Transceivers. Figure 1 shows the single-ended output volt-
age swing. Figure 2 shows the peak-to-peak differential out-
put voltage. Consult the Virtex-4 RocketIO Multi-Gigabit
Transceiver User Guide for further details.

Notes:
1.
The maximum VTRX is 1.26V when bypassing the internal AC coupled VICM. VTRX must be less than or equal to AVCCAUXRX.
2.
The output swing and pre-emphasis levels are selected using the attributes discussed in Chapter 4: PMA Analog Considerations in the Virtex-4
3.
VTTX is 1.5 ± 5%; different amplitudes possible with adjusted DAC values.
