  • RE: AM62X-PET-CALC: How to use the AM62x Power Estimation Tool

    Hi Daisuke-san, Daisuke Maeda said: Was a heatsink used for the AM62x on the board used for measurements in the application note? There was not one used. Instead a Thermal Flow System, TFS. Daisuke Maeda said: What is the airflow (m/s) under temperature…

  • AM62X-PET-CALC: I2C port

    Part Number: AM62X-PET-CALC Hello TI Expert In I2C specification , there are tf item listed , the min tf = 12ns when in Fast mode. But in AM62x MAIN_I2C port , the tf can't meet >12ns requirement. Can we modify the I2C output slope in AM6204? …

  • AM62X-PET-CALC: RGM II SRi test fail

    Part Number: AM62X-PET-CALC Hello TI Expert In RGMII specification , in my design we can't meet the min SRi = 2.64ns spec item. We has tried to modify the ETH phy(88Q1110) into the max driver strength mode, and the test result is 1.8V/ns. Any suggestion…

  • AM62X-PET-CALC: Power consumption assessment

    TI Thinks Resolved
    Part Number: AM62X-PET-CALC Hi TI I use the Power consumption assessment sheet provided by TI. When i select HS200 +Utilization 100%, but 0mA SOC_DVDD1V8 current result is show which not make sense, as the SOC_DVDD1V8 is connect to VDDSHV4 port which…

  • AM62X-PET-CALC: CSI waveform review

    Part Number: AM62X-PET-CALC Hi TI As you know , we can't test the SOC die side wavefrom but can only test the CSI nearest test point nearby SOC. We found the waveform of CSI has non-monotonicity rising edge at nearby SOC side test point, whether this…

  • AM62X-PET-CALC: AM6204 ibis model

    Part Number: AM62X-PET-CALC Other Parts Discussed in Thread: AM625 Hi TI I download the SPRM 766 as the AM62x IBIS model , but found the pin net can't match with AM6204_AMC 's net. For example , F20 in ibis is RESET_REQZ, but in schematic RESET_REQZ…

  • AM62X-PET-CALC: Crystal Vin_h spec

    Part Number: AM62X-PET-CALC Hello TI expert We test the Crystal start up waveform, and found the Vout_high is around 960mv which is lower than spec listed 0.65xVDDS_OSC0, how to fix this spec violation item? Same issue for RTC crystal signal level. …

  • AM62X-PET-CALC: What's the SRi paraemeter meaning?

    Part Number: AM62X-PET-CALC Hi TI expert For Reset input signal there are SRi parameter listed in Datasheet, but i feel confuse about which edge SRi should be monitored and why? For first power on stage, Reset pin 's rising time can't meet SRi > 3.3E…

  • RE: AM62X-PET-CALC: Abnormal LPDDR4 driver waveform

    Jingcheng, i did test with the 2.2K pulldown and did not see any voltage drop like you show on the 10K pulldown scope shot. The RESET signal was stable once it went high. The register fix should clean up that signal, that is why i was suspecting the register…
