ANA#19

Bandgap Decoupling Capacitor On-Board

Revision(s) Affected:

AWR6843 ES2.0

Description:

A 47-nF capacitor is needed on the bandgap pin. Not having correct capacitor on this pin, can cause boot up issues, especially, at negative temperatures. This requirement is being Included in the errata, as it is a recent change which may not be updated in older reference designs.

Workaround(s):

Use the recommended 47-nF capacitor. For example: part - GRM155R71E473KA88 (see the device-specific EVM and Reference Design files for updated part).
