DS90UB954-Q1: Is there any risk for full AEQ range

Part Number: DS90UB954-Q1
Other Parts Discussed in Thread: ALP

Hi, TI team

I changed AEQ to all TI recommended areas (0x51 -> 0xE0),
but is there any risk that the setting is incremented every time LOCK is released?
Also, please tell me the role of SFILTER, which is not listed in the document.
During 10/28.

Hello Peiyq,

The sfilter is described in this document:

I’m not sure what register you are referring to since 0x51 is not related to AEQ on the 954.

Best Regards,

Casey

Hi Casey

I changed the register address 0xD5's (AEQ_MIN_MAX) data from 0x51 to 0xE0.

Hello Peiiyq,

The AEX min/max acceptable values can be qualified using the MAP tool in ALP. If those values are passing for your system then it would be ok to change this value.

Best Regards,

Casey

Hello Peiyq,

When using 954 in 4G mode, I would suggest simply sticking with the default register value as long as the MAP tool results look acceptable.

Best Regards,

Casey
