These oscillators can also be reprogrammed from MSP430 system controller U38 (see TI
MSP430 System Controller on the
information and the ZCU216 web page for the ZCU216 System Controller GUI Tutorial (XTP_TBD).

User SMA MGT Clock

[Figure 2, callout 34]
The ZCU216 board provides a pair of SMAs (J6, J7) for differential AC coupled user MGT clock
input into Zynq UltraScale+ RFSoC U1 GTY Bank 130. This differential signal pair is series-
capacitor coupled. The P-side SMA J6 signal USER_SMA_MGT_CLOCK_P is connected to U1
MGTREFCLK1P pin M34, and the N-side SMA J7 signal USER_SMA_MGT_CLOCK_N is
connected to U1 MGTREFCLK1N pin M35. The user SMA MGT clock differential signal
amplitude must not exceed -0.5V (Min) to 1.30V (Max).
The detailed RFSoC connections for the feature described in this section are documented in the
ZCU216 board XDC file, referenced in

zSFP/zSFP+ Module Connectors

[Figure 2, callout 15]
The ZCU216 board hosts a quad zSFP/zSFP+ connector (J29) that accept zSFP or zSFP+
modules. The connectors are housed within a single 2x2 zSFP cage assembly. The following
figure shows the zSFP/zSFP+ module locations within J29.
