(Note this question has been edited and simplified from the original post)
I am looking to clarify some of the crystal oscillator specifications for the S32K.
In Table 16 of the S32K datasheet, several values for g_m_xosc are specified:
I can see that the 4-8MHz vs the 8-40MHz can be selected through SCG_SOSCCFG (p572 S32K RM), but the datasheet does not seem to provide guidance as to whether the transconductance min/max values of 16mA/V and 47mA/V refer to "low-gain" or "high-gain" operation.
Are there differences in transconductance between these two modes?
