Hi,
My customer is considering replacing the crystal unit connected to the TTM4C1294KCPDTI3.
The specifications of C1 and C2 which are connected to OSC0 and OSC1 terminals are described in "Table 27 -23" in datasheet.
Table 27 -23 specifies Min 12pF to Max 24pF.
We understand that this value is defined by the load capacitance of the crystal unit connected to the OSC0 and OSC1 terminals.
Does it mean that the capacity within this specification (Min 12pF to Max 24pF) needs to be set as the TM4C1294KCPDT specifies this value?
In Table 27 -24, some model numbers (Example: NX5032 GA -16.000 MHZLN-CD -1) show values of 10pF for C1 and C2, which are out of specification(Min 12pF to Max 24pF) .
Could you tell me why the TM4C1294KCPDT specifies this value?
Currently, they are considering replacing it with a crystal oscillator with a load capacity of 6pF. In this case, the external capacitor capacitance of C1 and C2 is likely to be 8pF or 9pF, which deviates from the specifications of C1 and C2 in Table 27 -23.
Best Regards,
O.H
