    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.
