Hi Raghavendra,
both even and odd harmonics exist but odd harmonics are usually higher than even harmonics.
Your output power setting is 7, could you make it to 30?
I don't know the harmonics required from ADC, you'd better check with the ADC team…
Hi Kang,
It would be best to use this jitter calculator and the phase noise specs from the LMK datasheet in order to understand the degradation and tradeoffs of using the LMK or any other clocking device you might want to use.

Part Number: TPSI31XX-CALC Other Parts Discussed in Thread: TPSI3050-Q1 I am trying to load the model of TPSI3050-Q1 PSPICE model into TINA using New Macro Model. But its throwing syntax error. I tried both G and H versions. Can you please help? I tired…
Hi Sheetal Gupta ,
The original carrier frequency is 2.5 MHz. Look at the top and bottom of the first picture. You will see the undesired AM modulation. This low frequency modulation is only present at certain carrier frequencies.
Look at the second…
Hello Jeevan,
Lakhinana Jeevana Rao said: What is the real meaning of ENOB for every ADC Channel in MCU weather it is telling the True ADC in real time for example if it is 12 Bit ADC channel in theory but in practical it is acting as 11 Bit or 10Bit…

Part Number: AM62X-PET-CALC Hi TI Team, I am working on the Texas Instruments AM62x SoC platform and need clarification regarding access to MCU SPI0 from the Linux (A53) domain .
Current Understanding:
MCU SPI0 is part of the MCU domain (M4F subsystem…
The system supports up to 24 lines, configurable for single-, two-, or three-phase setups. Measurements are performed using three external 24-bit ADCs (ADS131M08), with a target accuracy of Class 0.1. Our architecture is based on the TIDA-010037 (or TIDA-010244/3) reference design, which also utilizes external ADCs and mentions harmonic calculations, though the order is not specified.
Hello Liam,
The calibration values have nothing to do with THD performance. You can leave these values at default and will still get the same AC performance results.
When connecting a single-ended source, you can expect a degradation in THD of about…
Hi Neel,
Thanks for your question. I can help support the ADC issues. Some questions:
What is the issue you are seeing when applying the signal directly to the ADC vs the issue when going through the OPA front-end? This will help isolate if the…
