Timing Characteristics
Data Sheet
46
V1.0, 2003-11
The timings listed in the AC Characteristics that refer to TCLs therefore must be
calculated using the minimum TCL that is possible under the respective circumstances.
The actual minimum value for TCL depends on the jitter of the PLL. As the PLL is
constantly adjusting its output frequency so it corresponds to the applied input frequency
(crystal or oscillator) the relative deviation for periods of more than one TCL is lower than
for one single TCL (see formula and Figure 11).
For a period of N
× TCL the minimum value is computed using the corresponding
deviation D
N:
(N
× TCL)
min = N × TCLNOM - DN, DN [ns] = ±(13.3 + N × 6.3) / fCPU [MHz]
(1)
where N = number of consecutive TCLs and 1
≤ N ≤ 40.
So for a period of 3 TCLs @ 20 MHz (i.e. N = 3): D
3 = (13.3 + 3 × 6.3) / 20 = 1.61 ns,
and (3TCL)
min = 3TCLNOM - 1.61 ns = 73.39 ns (@ fCPU = 20 MHz).
This is especially important for bus cycles using waitstates and e.g. for the operation of
timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train
generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter
is negligible.
Note: For all periods longer than 40 TCL the N = 40 value can be used (see Figure 11).
