Multiplexed I/O ﴾Mio﴿ Pins - Enclustra Mercury+ XU7 User Manual

Differential Inputs
Internal differential termination is not supported for the HD pins ﴾banks 47, 48﴿. All differential signal
pairs from both HD banks may optionally be equipped with 100
the module.
The resistor identifiers for each differential input pair can be retrieved from the Mercury+ XU7 SoC Mod‐
ule User Schematics [5].
Single‐Ended Outputs
There are no series termination resistors on the Mercury+ XU7 SoC module for single‐ended outputs. If
required, series termination resistors may be assembled on the base board ﴾close to the module pins﴿.
2.8.7 Multiplexed I/O ﴾MIO﴿ Pins
Details on the MIO/EMIO terminology are available in the Zynq UltraScale+ MPSoC Technical Reference
Manual [21].
Some of the MIO pins on the Mercury+ XU7 SoC module are connected to on‐board peripherals, while
others are available on the module connector. The suggested functions below are for reference only.
Always verify your MIO pinout with the AMD device handbook.
Table 10 gives an overview over the MIO pin connections on the Mercury+ XU7 SoC module. Only the
pins marked with "user functionality" are available on the module connector.
