SBAS649B June 2021 – June 2022 DAC12DL3200
PRODUCTION DATA
DAC12DL3200 contains a number of alarms that can be used to determine whether the DAC is operating optimally, marginally, or in a faulty state. These alarms are sticky, such that if an error occurs then the alarm will be set and remain set until 1’s are written to that alarm register to reset the alarm.
The alarms are not valid until the part is fully programmed and operating. At this point, the alarm registers should all be cleared. They can then be monitored periodically, or by watching the ALARM pin, to determine if an alarm has occurred. The alarms that trigger the ALARM pin can be selected by unmasking the alarms in register ALM_MASK.
If an alarm occurs, the DAC can be programmed to mute the output signal until all alarms have been cleared. When this occurs, the faulty condition should be fixed by the system before resuming operation.
The alarms include:
LVDS Strobe alarm
