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.

Figure 4.1. Power Supply Block
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.
