Electrical characteristics
23.8.8
200/239
Due to this adaptation to the input clock, the frequency of f
locked to f
individual TCLs.
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 real minimum value for TCL depends on the jitter of the PLL. The PLL tunes f
keep it locked on f
one TCL period.
This is especially important for bus cycles using wait states and e.g. for the operation of timers,
serial interfaces, etc. For all slower operations and longer periods (such as, for example, pulse
train generation or measurement, lower baud rates) the deviation caused by the PLL jitter is
negligible. Refer to next
Voltage controlled oscillator
The ST10F276Z5 implements a PLL which combines different levels of frequency dividers
with a Voltage Controlled Oscillator (VCO) working as frequency multiplier. The following
table presents a detailed summary of the internal settings and VCO frequency.
Table 98.
The PLL input frequency range is limited to 1 to 3.5 MHz, while the VCO oscillation range is
64 to 128 MHz. The CPU clock frequency range when PLL is used is 16 to 64 MHz.
