The Trenz Electronic TE0782 is a high-performance, industrial-grade SoM (System on Module) with industrial temperature range based on Xilinx Zynq-7000 SoC (XC7Z035, XC7Z045 or XC7Z100).
...
The Trenz TE0782 SoM is equipped with two quad DC-DC voltage regulators to generate required on-board voltage levels 1V, 3.3V, 1.8V, 1.2V_MGT, 1V_MGT. Additional voltage regulators are used to generate voltages 1.5V, VTT, VTTREF and 1.8V_MGT.
There are following dependencies how the initial voltages of the power rails on the B2B connectors are distributed to the on-board DC-DC converters, which power up further DC-DC converters and the particular on-board voltages:
Power-on sequence is handled by the System Controller CPLD using power "Power good feedback "-signals from the voltage regulators.:

| To avoid any damage to the SoM, check on-board voltages in steady state before applying VCCIO voltages to the SoC's I/O banks. |
