Signal List By Ball Location
Table 1 presents the signal list sorted by ball number. When designing a board, make sure that the power rail for each signal is
appropriately considered. The specified power rail must be tied to the voltage level specified in this document if any of the
related signal functions are used (active)
Note:
The information in Table 1 and Table 2 distinguishes among three concepts. First, the power pins are the balls of the
device package used to supply specific power levels for different device subsystems (as opposed to signals). Second,
the power rails are the electrical lines on the board that transfer power from the voltage regulators to the device. They
are indicated here as the reference power rails for signal lines; therefore, the actual power inputs are listed as N/A
with regard to the power rails. Third, symbols used in these tables are the names for the voltage levels (absolute,
recommended, and so on) and not the power supplies themselves.
