Power Supply
A/D Power Supplies (U6, U7, U8)
The power supply block distributes clean power from the 12-V and 3.3-V input
supply (from the host board through the HSMC connector) to the Data Conversion
HSMC through on-board regulators. To provide various voltage options, the board
uses several Linear Technologies regulators.
Table 2–21 lists the Power Supplies board reference and manufacturing information.
