Zynq Ult RFSoC
The ZCU1285 board is populated with the XCZU39DR-2FFVF1760I Zynq Ult RFSoC at
U1 (callout 35,
Figure 2: Board Component Locations
). For further information on Zynq
Ult RFSoCs, see the UltraScale Architecture and Product Data Sheet: Overview (
RFSoC Configuration
The RFSoC is configured using one of the following options:
• Digilent embedded USB JTAG connector (callout 8,
Figure 2: Board Component Locations
• Xilinx Platform Cable USB II JTAG cable connector (callout 9,
)
The ZCU1285 board comes with an embedded USB-to-JTAG configuration module (Digilent, J69)
which allows a host computer to access the board JTAG chain using a Standard A to Micro-B
USB cable. Alternately, a JTAG connector (J2) is available to provide access to the JTAG chain
using the Xilinx Platform Cable USB II or compatible configuration cable.
The JTAG chain of the board is illustrated in the following figure. By default, only the RFSoC is in
the chain. Installing a shunt at J6 adds the FMC interfaces to the chain.
