The following sections include illustrations and tables of clock diagrams, signals, and parallel I/O outputs and inputs. When
systems such as DSP farms are developed using the DSI, use a device loading of 4 pF per pin. AC timings are based on a 20 pF
load, except where noted otherwise, and a 50 Ω transmission line. For loads smaller than 20 pF, subtract 0.06 ns per pF down
to 10 pF load. For loads larger than 20 pF, add 0.06 ns for SIU/Ethernet/DSI delay and 0.07 ns for GPIO/TDM/timer delay.
When calculating overall loading, also consider additional RC delay.

These are typical values at 65°C. The impedance may vary by ±25% depending on device process and operating temperature.
Start-Up Timing
Starting the device requires coordination among several input sequences including clocking, reset, and power. Section 2.5.3
describes the clocking characteristics. Section 2.5.4 describes the reset and power-up characteristics. You must use the
following guidelines when starting up an MSC8126 device:

Note:
PORESET and TRST must be asserted externally for the duration of the power-up sequence. See Table 11 for timing.
If possible, bring up the V DD and V DDH levels together. For designs with separate power supplies, bring up the V DD
levels and then the V DDH levels (see Figure 7 ).
CLKIN should start toggling at least 16 cycles (starting after V DDH reaches its nominal level) before PORESET
deassertion to guarantee correct device operation (see Figure 6 and Figure 7 ).
CLKIN must not be pulled high during V DDH power-up. CLKIN can toggle during this period.
See Section 3.1 for start-up sequencing recommendations and Section 3.2 for power supply design
recommendations.
The following figures show acceptable start-up sequence examples. Figure 6 shows a sequence in which V DD and V DDH are
raised together. Figure 7 shows a sequence in which V DDH is raised after V DD and CLKIN begins to toggle as V DDH rises.
