I am currently working on DSADC in TC37 microcontroller. Here in the user manual, the following info is mentioned regarding passband frequency.

"Related to hardware characteristic for passband frequency ≤ 10 kHz the FIR1 has to be used with a decimation rate of 1:1." [Source: AURIXTC3XX_um_part2_v2.0 (1) (1).pdf (Page : 1366)]

Is the above passband frequency referring to input analog signal's frequency? Also it is mentioned to use FIR1 filter for passband frequency ≤ 10 kHz. Does anyone the reason for the need to enable FIR1 filter here?

Hello,

I am trying to increase the CPU lock so first I tried one of the existing examples:

CCU_Clock_1 for KIT_AURIX_TC397_TFT (imported/downloaded directly in Aurix Studio). Here is the link to the example code on github: https://github.com/Infineon/AURIX_code_examples/tree/master/code_examples/CCU_Clock_1_KIT_TC397_TFT 

Kit: https://www.infineon.com/cms/en/product/evaluation-boards/kit_a2g_tc397_3v3_tft/ 

According to the documentation there should be 100MHz clock on P23.1 --> I am only seeing 1MHz

Checked the crystal on the PCB and measured the signal on the XTAL inputs --> 20MHz crystal is connected (as expected from the Kits Datasheet)

I tried changing the N,K,P factors and I can see changes on the output. But there is no way I can achieve 100Mhz or higher like this.

My goal would be to achieve 300MHz CPU clock.

Any ideas why the clock output frequency would be so much lower than expected? I would go on and check each register setting related to the clock but with no expectation to find anything, some guidance would be appreciated.

Hello Support,

We have been trying to understand the ESM present in manual AURIX TC3xx Safety Manual v2.0 1.pdf

Please help me to understand this concept so that I get the complete picture before implementing this ESM.

Thanks & Regards,

AF
