Board Components and Interfaces
Level Translator Bidirectional level shift interface
The board provides bidirectional level shift feature for the 2.5V input
(Cyclone III FPGA) and 3.3V required by many of the interface chips via
two Maxim MAX3378 level translators.
Table 2–5 lists bidirectional level
shift interface reference and manufacturing information.
Figure 2–4 shows the block diagram and pinout of the bidirectional level
shift interface on the board respectively.
