KE1xZ LPFLL frequency range question

isaotakashima — Thu, 15 Mar 2018 08:43:11 GMT

According to feature in the KE1xZ reference manual, LPFLL has below feature.

• Programmable multiplier for up to 4 different frequency ranges

But I found only the following two frequency ranges.

00 LPFLL is trimmed to 48 MHz
01 LPFLL is trimmed to 72 MHz

Does the LPFLL of KE1xZ have the remaining two frequency ranges except the above?

Please reply as soon as possible.

Best regards

Takashima

Hi Takashima,

Yes, I think you are right. Programmable multiplier for only 2 different frequency ranges. I'll report this problem to internal system.

Thanks!

Hi Takashima,

KE1xZ LPFLL supports 2 trimmed frequency ranges, will update the LPFLL descriptions in RM.
