• UART to SC
• UART to MPSoC ZU19
• UART to RFSoC ZU21
UART
There are three UARTs on the T1 card:
• SC (satellite controller)
• MPSoC ZU19
• RFSoC ZU21
The UART signaling to the SC has been set to 115.2K baud and 8N1 bits/parity/stop. The UART
signaling to the MPSoC ZU19 and RFSoC ZU21 are as specified by the specific image.
JTAG
The JTAG chain on the T1 card provides access to both the MPSoC ZU19 and RFSoC ZU21
devices and is automatically recognized by the Xilinx toolchain when a USB connection is
present.
Refer to
Appendix A: Programming the Devices Using JTAG
for further details.
IEEE 1588 Support
The T1 card card supports
and extracts time and phase information from incoming
IEEE 1588 packets on the SFP28 ports. External clock synchronization is provided over PPS
in/out SMA connectors located on the front I/O bracket as shown in the following figure.
