CLOCK AND TIMING CHARACTERISTICS (Cont’d)
10.5.4 RC Oscillator
The ST6 internal clock can be supplied with an external RC oscillator. Depending on the
accuracy of the frequency is about 20%, so it may not be suitable for some applications.

Notes:
1. Data based on characterization results, not tested in production. These measurements were done with the OSCin pin
unconnected (only soldered on the PCB).
2. R
must have a positive temperature coefficient (ppm/°C), carbon resistors should therefore not be used.
