2.6 AC Timings
The following sections include illustrations and tables of clock diagrams, signals, and parallel I/O outputs and
inputs. AC timings are based on a 50 pF load, except where noted otherwise, and 50 Ω transmission line.
2.6.1
2.6.2
Starting the device requires coordination among several input sequences including clocking, reset, and power.
Section 2.6.3 describes the clocking characteristics. Section 2.6.4 describes the reset and power-up characteristics.
You must use the following guidelines when starting up an MSC8101 device:
The following figures show acceptable start-up sequence examples. Figure 2-4 shows a sequence in which
