OPERATING CONDITIONS
(Cont’d)
The RC oscillator and PLL characteristics are temperature-dependent and are grouped in four tables.
13.3.5.1 Devices with ‘”6” or “3”order code suffix (tested for T
A
= -40 to +125°C) @ V
DD
= 5V
Notes:
1.
If the RC oscillator clock is selected, to improve clock stability and frequency accuracy, it is recommended to place a
decoupling capacitor, typically 100nF, between the V
DD
and V
SS
pins as close as possible to the ST7 device.
2.
See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 23
3.
Data based on characterization results, not tested in production
4.
Averaged over a 4ms period. After the LOCKED bit is set, a period of t
STAB
is required to reach ACC
PLL
accuracy.
5.
After the LOCKED bit is set ACC
PLL
is max. 10% until t
STAB
has elapsed. See
Figure 13 on page 24
.
6.
This period is the phase servo loop period. During this period, the frequency remains unchanged.
7.
Guaranteed by design.
