Table 11: MIO Pins Connections Overview
2.10 Multi-Gigabit Transceiver (MGT)
On the Mercury ZX1 SoC modules equipped with bigger SoC devices, there are eight Multi-Gigabit transceivers
and four reference input clock differential pairs available on the module connector B.
On the Mercury ZX1 SoC modules equipped with smaller SoC devices, there are only four Multi-Gigabit
transceivers and two reference input clock differential pairs available. Instead, on these modules, there are
additional regular I/Os routed to the module connector. Please refer to Section 2.9.2 for details on the MGT
connections for different SoC devices.
Table 12 lists the available speeds for the MGT lines on the SoC device. Refer to Section 2.2 for details on
the module configurations and equipped SoC devices.

UART RX is an SoC input; UART TX is an SoC output.
