Detailed Description
R
Single-Ended Expansion I/O Connectors
Header J6 contains 32 single-ended signal connections to the FPGA I/Os. This permits the
signals on this connector to carry high-speed, single-ended data. All single-ended signals
on connector J6 are matched length traces. The V
CCIO
of these signals can be set to 2.5V or
3.3V by setting jumper J20. Table 1-10 summarizes the single-ended connections on this
expansion I/O connector.
