Preliminary—Subject to Change without Notice
1.3.2 AC Electrical Characteristics
This section provides the clock and AC electrical characteristics for the 603.
1.3.2.1 Clock AC Specifications
Table 5 provides the clock AC timing specifications as defined in Figure 1. These specifications are for 25,
33.33, 40, 50, and 66.67 MHz bus clock (SYSCLK) frequencies.
