11.1 Absolute Maximum Ratings
Table 11-1 specifies the absolute maximum ratings that should never be exceeded. Exceeding the
specified absolute maximum ratings may damage the ASIC. These ratings are guidelines for absolute
worst case operating conditions and should not to be interpreted as recommended operating condition.
