SWRZ074C May 2017 – May 2021 IWR1443
Unreliable Readings from Synthesizer Supply Voltage Monitor
IWR1443 ES1.0, IWR1443 ES2.0, and IWR1443 ES3.0
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.
Ignore the field STATUS_SUPPLY_PMCLKLO in the monitoring report message: AWR_MONITOR_PMCLKLO_INTERNAL_ANALOG_SIGNALS_REPORT_AE_SB.
