Hello Team,
My customer has some problems with the ADS5294.
1. The register 28 shows which output format is provided on the LVDS interface.
- In Word-Wise mode, something seems not to be set correctly in the module, since in this mode individual channels produce data errors for individual ICs (but not for a test ramp). Did this error occur in Word-Wise mode? We have been using the BIT-Wise mode since then
- According to the documentation and the table in the appendix, the BIT-Wise mode should be set at the highest D15 = 0 and D7 = 1. This can not be entered at all. Only D15 = 1 and D7 = 1 are possible. The output data then looks as if it were the BIT-Wise mode. Is our assumption correct here?
2. In register 29, the flag for GLOBAL_FILTER_EN and EN_CHANNEL_AVG can be set.
Here I can not set the bit for GLOBAL_FILTER_EN (as well as for the Averaging). Although the BIT GLOBAL_FILTER_EN is not set, ie 0, the high-pass filter appears to be switched on. Is the low-pass decimation filter connected? Why is it not possible to set the GLOBAL_FILTER_EN bit?
Thank you. Looking forward to hear from you.
Best,
Needhu
