LC651431L and LC651432L RC Oscillator Characteristics
Figure 8 shows the LC651431L and LC651432L RC oscillator characteristics.
However, the LC651431L and LC651432L have the following RC oscillator frequency sample-to-sample variations.
V
DD
= 2.2 to 6.0 V, Ta = –40 to 85°C
When the external circuit constants are: Cext = 220 pF, and
Rext = 12 k
, the frequency range will be:
200 kHz
≤
f
MOSC
≤
790 kHz
Note that only the above circuit constants are guaranteed.
If using other values for these constants is unavoidable, use values in the following ranges.
Cext = 150 to 390 pF
Rext = 3 to 20 k
(See figure 8.)
Notes: 10. The oscillator frequency must be in the range 350 to 500 kHz when V
DD
= 5.0 V and Ta = 25°C.
11. Applications must assure adequate margins so that oscillator frequency falls in the operating clock frequency range (in the oscillator divider option
table) for the ranges V
DD
= 2.2 to 6.0 V and Ta = –40 to 85°C.
