Multi-Gigabit Transceiver (MGT)

There are six Multi-Gigabit transceivers and two reference input clock differential pairs on the Mercury SA1
SoC module routed directly to the module connector B.
The transceivers on the SoC device support a data rate of 3.125 Gbit/sec.
Warning!
The maximum data rate on the MGT lines on the Mercury SA1 SoC module depends on the routing
path for these signals. Adequate signal integrity over the full signal path must be ensured when using
MGTs at high performance rates.

eMMC flash interface is available starting with revision 3.
