2 Electrical Characteristics
This document contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing
specifications. For additional information, see the MSC8154E Reference Manual.
2.1 Maximum Ratings
In calculating timing requirements, adding a maximum value of one specification to a minimum value of another specification
does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values
in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction.
Therefore, a “maximum” value for a specification never occurs in the same device with a “minimum” value for another
specification; adding a maximum to a minimum represents a condition that can never exist.
Table 2 describes the maximum electrical ratings for the MSC8154E.

Notes: 1. Functional operating conditions are given in Table 3.
2. Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the listed limits may affect device reliability or cause permanent damage.
3. PLL supply voltage is specified at input of the filter and not at pin of the MSC8154E (see Figure 37 and Figure 38)
