Reference Schematic and Signal Naming
In compliance with the Low-Voltage Transistor-Transistor Logic
(LVTTL) specification.
In compliance with the Low-Voltage Complementary Metal Oxide
Semiconductor (LVCMOS) specification.
Pull-up During Configuration
The temperature reported digitally by a sensor that measures the die
junction temperature of the Xilinx Zynq SoC.
The temperature reported digitally by a sensor on the Xilinx Zynq SoC
side of the circuit card assembly underneath the integrated heat
spreader. This value is an approximation of the local ambient
temperature inside the heat spreader.
The temperature reported digitally by a sensor on the SEARAY side
of the circuit card assembly. This value is a conservative
approximation of the local ambient temperature on that side of the
circuit card assembly.
