CC1310: Internal capacitor array minimum configurable value

franziskus

Part Number: CC1310

Team,

Is it possible to completely disable the internal capacitances to get a value approximately equal to zero pF?
(except for parasitics)

Or is there always a residual capacitance value of the array? For that case, what is the minimum configurable capacitance?

Thanks!

This: processors.wiki.ti.com/.../CC13xx_CC26xx_Crystal_Tuning contains the measured load cap for a wide number of settings. As this shows, it's not possible to turn off the array, only to turn it to a minimum. Hence the array will give a small residual cap in addition to the external parasitics.
