Figure 5 below demonstrates how to connect the JTAG-SMT3-NC () to Xilinx’s Zynq-7000 silicon alongside Xilinx’s 14-pin JTAG header.
In this example, an open drain buffer allows both the SMT3-NC () and Xilinx JTAG Header to drive the PS_SRST_B pin, which may
operate a different voltage than the Zynq’s JTAG pins.
