Chapter 2: System Description

This chapter gives essential electrical and mechanical specifications for the EB1200M62-355JC evaluation board.

2.1 Key Specifications

Table 1 lists the absolute maximum ratings of the EB1200M62-355JC evaluation board. Note that this table contains only
key parameters. Constraints from the ACPL-355JC, ACPL-C87B, and ACPL-736J data sheets, as well as specification of
other key components, must be considered when the EB1200M62-355JC is used.
