Unreliable Readings from Synthesizer Supply Voltage Monitor

Revision(s) Affected:

IWR1642 ES1.0 and IWR1642 ES2.0

Description:

During monitoring, the thresholds used to determine if the synthesizer supply voltage is within limits are much stricter than necessary for proper circuit operation. This can lead to occasional, erroneous reporting of supply failures even when there is no adverse impact on circuit or system behavior.

Implication: The user cannot rely on supply failure indication from the supply monitors of PM, Clock and LO subsystems. The affected field is STATUS_SUPPLY_PMCLKLO in the monitoring report message: AWR_MONITOR_PMCLKLO_INTERNAL_ANALOG_SIGNALS_REPORT_AE_SB.

Workaround(s):

Ignore the field STATUS_SUPPLY_PMCLKLO in the monitoring report message: AWR_MONITOR_PMCLKLO_INTERNAL_ANALOG_SIGNALS_REPORT_AE_SB.
