Part Number: LM5025
Hi Team,
I have two questions for about VREF and RAMP clamp level.
-----------
[Q1]
We understand that VREF and Ramp clamp level are shown in the datasheet.
However, we would like to know Distribution data of VREF and RAMP clamp level.
Would you send it if you have this data?
[Q2]
We need high accuracy of VREF and RAMP clamp level.
So, could you please let us know if you have a recommended other device?

Part Number: OPA857
Hi Experts,
Our customer wants to know the silicon process for OPA857IRGTR, is it based on CMOS process or others? Can you help to check?
Thanks.
Part Number: TPS61194
Hi,
As per the datasheet, the supported PWM freq is 100Hz to 20KHz.
Can we give PWM with a frequency more than 20KHz?
Because of the PWM switching, the ripple on the voltage rail is very high.
If we make the PWM as high, the ripple is less.
Also increasing the PWM frequency results in reduction in ripple voltage.
So whether we can use frequency higher than 20KHz?
It may help us to reduce the ripple.
Please suggest whether we can use higher frequencies.
Thanks & Regards,
Shafeeq
Part Number: TDC1000-C2000EVM
Hi All,
I am working with TDC1000_c2000EVM software and I am using STEMINC 1MHZ ultrasonic transducer. The transducer is mounted inside the small piece of steel with cyanoacrylate glue and mounted the steel on the top of the plastic container.
here is the problem
1. I am trying to measure the distance from the top. When I measure TOF with an empty (Air) condition, I got some values. On trying with some material inside the Jar, the TOF value is random. In some cases the TOF value displayed is that of empty. I am not getting TOF value corresponding to that of material. The readings are varying from time to time.
This is my configurations
2. In oscilloscope, the time between the start and stop pulse is always 30-40us but in TDC1000_c2000evm software TOF value is around 550us when I enabled blanking the time is 30us+blanking period time.
Please review and share your suggestions.

Part Number: CC3220MODA
Hi all, I'm newbie and I have a question
CC3220MODAx SimpleLink Wi-Fi Wireless MCU System-on-Chip (SoC) Contains a Single Chip With Two Separate Execution Environments:
– User Application Dedicated ARM® Cortex®-M4 MCU
– Network Processor MCU to Run All Wi-Fi and Internet Logical Layers
So how do they communicate with each other, what is the standard of communication?
Thanks a lot!

Part Number: ADS1292R
Hello we made our integration with the ECG chip and we have the problem that the ECG is moves around a lot and not stays by the 0 line. Please have a look at the html file but as preview you can see that pic. On the html file you can zoom.
When we did the schematic our HW developer was in contact with Tom from TI and the Schematic was changed to our needs together with him. We are using the ecg electrodes very close together only 3cm distance.
In the PDF file you can see out init process for the Chip and which settings we are using.
Can you please tell us what could be wrong and why the RLD is not working so the ECG is moving a lot and not realy stays on the 0 line?
Thank you
Regards Marc

Part Number: PROCESSOR-SDK-AM335X
Hi,
I am using SKAM335x board and SDK RTOS on windows Host PC.
I am using given example of watchdog timer. When counter value overflows, it should reset the system. I am not sure it is resetting system or not because it is printing some message on terminal as given below.
U-Boot SPL 2013.01.01 (Jun 25 2013 - 16:42:52)
Incorrect magic number (0xffffff09) in EEPROM
Could not get board ID.
Incorrect magic number (0xffffff09) in EEPROM
### ERROR ### Please RESET the board ###
Please help me in regarding this, whether it is working correctly or not.

Hi Vivek ,
Can you give me more details about DMM interface pin muxing ? Because we got some pin conflict issues .
here are my questions below :
1、Is the EN(NDMM_EN) N13 or N5 DMM signal necessary ? we don't find this signal on J3 (60PIN HD Connector)of DCA1000 .
2、N13 is currently in use by JTAG, pin TDO .How to deal with this pin ?
Thank you ,
Simon
Part Number: DDC114
Hello guys,
One of my customers is considering using DDC114 for their new products.
They have a question about DDC114 spec discription as the follow.
Q, DDC114 datasheet says that "±0.01% Reading ± 0.5ppm FSR, typ" and "±0.025% Reading ± 1.0ppm FSR, max" as "Integral Linearity Error(6)" characteristics on page 3 .
Could you please tell me what "±0.01% Reading ± 0.5ppm FSR, typ" and "±0.025% Reading ± 1.0ppm FSR, max" mean?
Your reply would be much appreciated.
Best regards,
Kazuya.

Part Number: AM3352
Hello,
My customers want to debug u-boot in Processor SDK for AM335x on their custom board.
And they want to repeat on and off for their custom board; however, they want their board to keep the debug connection.
Could you tell me the way to debug u-boot and keep debug connection for device on/off?
Best Regards,
Nomo
Part Number: AM3352
Hello,
We are using am3352 in our design with kernel 4.14.67 from TI SDK.
We are connecting an external USB modem and we want to use autosuspend/resume in order to save some power. To enable this option for our modem we have changed option_probe() function in drivers/usb/serial/option.c file:
if(serial->dev->descriptor.idVendor == cpu_to_le16(0x2C7C)) {
pm_runtime_set_autosuspend_delay(&serial->dev->dev, 3000);
usb_enable_autosuspend(serial->dev);
}
if (serial->dev->descriptor.idVendor == cpu_to_le16(0x2C7C)) {
device_init_wakeup(&serial->dev->dev, 1); //usb remote wakeup
}
We see that when there is no traffic USB enters in suspend mode, and also when host sends some new data it resumes and USB modem responds.
The problem is that USB modem is not able to wake host up while in suspend mode.
We contact USB manufacturer and they ask us to comfirm that am3352 can support autosuspend/resume feature. Could you please confirm this please?
If this is the case, do you know if we need to do something else to enable this feature?
Best regards and thank you

Part Number: TDA3LA
Tool/software: Code Composer Studio
Hello!
I have two different projects of ARM cores of TDA3 SoC. The first projects uses IPU_C0, and the second project uses IPU_C1. I can debug them all differently, but I need to debug it or run it simultaneously.
I tried to find out how to do this, but not successful.
Do I need to make a united project? Or I can do it from some debug file.
P.S.
I've found some threads and topics but there are not useful.
Part Number: AM3352
Hello,
on our hardware platform, we are using the CPSW as a single MAC interface. Receiving Ethernet packets is done with CPDMA support.
For the transmit direction, the "pass_crc" flag of the SOP descriptor can be used to select, if the provided packet already contains a frame CRC or not. In our case, "pass_crc" is not set. For the transmit direction, the same flag of the SOP descriptor indicated, if the received packet data contains a frame CRC.
In our configuration, the receive direction (Pass CRC) flag is always set. Is it possible to disable the forwarding of the receive CRC within the CPSW (or sowhere else)?
Thanks and best regards

Part Number: SN74LVC1T45
Hi,
I am going to use the SN74LVC1T45DCK.
I went over the datasheet, and I a bit confused regarding state 1 in table 3 (page 14)
As far as I understand when Dir control = H, I would expect the IO1 to be In and IO2 to be Out, however it is opposite in the table.
Is this ok?
Best regards,
Moshe

As per my design i need to configure PRU1, and PRU2 as ethernet.
In SDK i by default PRU0 and PRU1 is configured as ethernet ( binaries are available for PRU0 and PRU1 only)
Please let me know how to get binaries for PRU2 and kernel configurations to enable PRU2 - ethernet port ( DTS changes )

In the AM335x data sheet, Input leakage current with Receiver disabled (II) is defined, but Input leakage current with Receiver enabled is undefined.
Could you tell me the Input leakage current with Receiver enabled for each terminal?

Part Number: TXS0108E
Hi Team,
In TXS0108E datasheet, I saw Data rate - Pushpull max is 60Mbps, does that mean if the output is push-pull method, the output data rate is 60Mbps max, meanwhile, if the output is open-drain, the output data rate is 2Mbps max, right?
