4.3 DC Power Interface
The DC power interface consists of the DC power inputs as summarized in
Table 8
. The power
requirements apply to DC power measured at the Tile user connector input and not at the output
of the power supply. It is required that users incorporate the required bypass capacitors for the
supplied power input as can be seen in
Figure 5.

Table 8:
Power supply characteristics for 3.15, 3.30, and 3.60V supplies to the Tile.
*Includes satellite receiver active current with GPS in acquisition mode. The Tile enters into GPS acquisition mode for
approximately 30 seconds after exiting from sleep mode, on powerup, or when the Tile needs to re-acquire a GPS fix
(approximately once every 3 hours) while the Tile is continuously powered on and not in sleep mode.
