4. Power Supply
The power supply to the development kit is provided by the Mini-B USB connector or from an external adaptor.
Figure 4.1
shows the power supply block of the CrossLink LIF-MD6000 Master Link board. The Mini-B USB connector is
used only for programming and the onboard power regulator for the successful programming. The external adaptor
provides 12 V power source through voltage regulators on the board to CrossLink and LCMXO3LF-1300E, as well as to
the external boards connected to Tx and Rx Headers. Each I/O and core voltage rail on the board is accessible by a test
point on the board. The current flowing to each rail can be measured using a 1 Ω resistor placed in the path of each
voltage rail.

Table 4.1
lists the device power rails. There are five voltage regulators on the board used to supply the 5 V, 3.3 V, 2.5V
1.8 V, and 1.2 V rails. The input to these regulators is either from the Mini-B USB connector or the external 12 V
adaptor that is connected to the board. Switch SW2 is used to connect or disconnect the external adaptor power to the
board.
