Part Number:CDC3RL02
Dear BU experts,
Would you confirm below question ?
In datasheet, The min spec of CLDO is 1uF. Does this include the tolerance of cap(1uF) ? So, customer must use higher value than 1uF considering the cap's tolerance itself.. Right ?
Thanks,
JH.

Tool/software:TI-RTOS
Hi Sir
I have some questions about ADS1292 schematics design questions as followings.
My application is two polarities at CH1.
There are two ways for RLDIN and RLDOUT connected with AVDD without RLD function.
Could you share some comments with me? Thank you a lot.
Part Number:DRA750
Hi
As we know there is an internal-built thermal sensor in DRA75x series SOC to report CPU junction temperature,
does anyone know the tolerance for this thermal sensor?
I can't find this information on the datasheet.

Hi,
May I know how to disable 'Ping' feature which are automatically enabled in BLE SDK 3.0?
The end customer only support BLEv4.0 on their host but the slave unit which uses the SDK 3.0 keeps sending PING_REQUEST which is not supported on the host, which also causes extra power consumption.
Pls help to advise what's the way to disable 'Ping' feature.
Thanks!

Hi engineers,
I am looking for a ADC solution of sample rate>2G, ENOB equals to 12bits solution, and I haven't found on the TI website, could anyone give me some help? I do not have other requirements, and also can accept two pieces of ICs to implement my application.
Thanks!

Hi,
From www.ti.com/.../sprufn3d.pdf, GPADIR is 0 (input) after reset, GPAPUD (for GPIO0~GPIO11) is 1 (disabled) after reset, I am able to confirm this via CCS Register Viewer.
When I enable the pull-up for GPIO1, the Halt mode power consumption will be almost 200uA (case 2), but if I set the write 0 to GPADIR again (see case 3), the power consumption returns to 50uA correctly.
As you can see for all cases the GPADIR is always 0 for GPIO1 (default value after reset) and there is no difference in register values for case 2 vs case 3. Any explanation to this behavior?
The pin is floating on my board, so my intention is to leave it as input and enable its pull-up.
Case 1)
GPIO_setMode(obj->gpioHandle,GPIO_Number_1,GPIO_1_Mode_GeneralPurpose);
GPADIR = 0x00010000
GPAPUD = 0x00010F17
GPADAT = 0x300E10EA
Halt mode total current: 54.4uA
Case 2)
GPIO_setPullUp(obj->gpioHandle,GPIO_Number_1,GPIO_PullUp_Enable);
GPIO_setMode(obj->gpioHandle,GPIO_Number_1,GPIO_1_Mode_GeneralPurpose);
GPADIR = 0x00010000
GPAPUD = 0x00010F15
GPADAT = 0x300E10EA
Halt mode total current: 189.5uA
Case 3)
GPIO_setPullUp(obj->gpioHandle,GPIO_Number_1,GPIO_PullUp_Enable);
GPIO_setDirection(obj->gpioHandle,GPIO_Number_1,GPIO_Direction_Input);
GPIO_setMode(obj->gpioHandle,GPIO_Number_1,GPIO_1_Mode_GeneralPurpose);
GPADIR = 0x00010000
GPAPUD = 0x00010F15
GPADAT = 0x300E10EA
Halt mode total current: 54.4uA
Thanks,

Hi Team,
If the TAS57xx series includes the 96k sample rate DSP, can be support the 20Hz to 40kHz frequency response?
Part Number:CC2640

Hi:
Ti engineer!
I use the example of C:\ti\simplelink\ble_sdk_2_02_01_18\examples\cc2650lp\simple_peripheral example, modify the chip to be packaged as 4XS, and the power consumption of the broadcast is 1.4 mA, and how I should be able to achieve uA. POWER SAVING has been defined, and display is closed.
Thanks!
Part Number:MSP432P401R
Tool/software:TI-RTOS
Hi everyone,
I am using MSP432 Evaluation Kit and sending data via UART using TI-RTOS api (UART_write and UART_read, Baud rate is 115200). However, I found there are a lot of data losses in UART after sending around 50 bytes (before 50B is ok). To solve the problem, I tried a loopback test using UART Echo demo and I got the same result. After looking into the codes in MSP_EXP432P401R, I found I can use a larger ring buffer size (default is 32 B) and I changed the size to 512 B, after which I made it to work without data loss.
Is there any other way to solve the problem? Looks like a big buffer isn't a good solution.
Any suggestion is helpful.

Part Number:DAC38J84
I am using DAC38j84 to generate a Fo=800MHz,BW=100MHz chip signal, a transformer ADTL2-18 is uesd to output a signle-ended waveform.
a LC-filter is needed to filter out the mirror image,here is my question:
Should i use a differential LC-filter before transformer or a signle-ended LC-filter after ADTL2-18?Which is better in the actual application?Why?
Looking forward to your reply
Thanks

Part Number:TMS320C6678
Hi, this question actually is quite generic. The NDK has not been updated for a long time. It seems that there will only be bugfix updates, but no new feature any more in the future. The NIMU driver for c6678 is also a little buggy, and no more bugfix updates.
So I have to ask some questions:
Thank you.
Part Number:CC2640R2F
Hi,
Could you give me advice the reason for “Exception handing issue”?
* Device: CC2640
* Evaluation Board: Customer’s board
* Error message:
Ti_sysbios_family_arm_m3_Hwi_excHandler__I(unsigned int*, unsigned int) at Hwi.c:877
When the above error message is printed?
How to solve it?
Part Number:CC2530
Hi. My setup is I have a ZED and its parent as Router 1. I also have another Router 2 that has no ZED connected to it. When I disconnect the power from Router 1, the ZED doesn't seem to connect to Router 2. It's just looking for Router 1. How can I make it so when the ZED loses connection with it's parent, it can still connect back to the network, but through Router 2? (In Z-Stack 3.0 SampleLight)
Part Number:DP83822I
Hi,
I have a question about DP83822I reset timing.
From the datasheet of DP83822I, I couldn't find the timing specification
between VDDIO/AVD and Hardware RESET_N.
Are there any timing specification between VDDIO/AVD and Hardware RESET_N?
What I want to know is,
does Hardware RESET_N need to be deasserted after VDDIO/AVD have been stabilized?
If yes, how long should RESET_N need to be assert after VDDIO/AVD have been stabilized?
From the datasheet of DP83822I, I couldn't find the above timing specification.
best regards,
g.f.
Part Number:ADS1278EVM-PDK
I made a ADS1274 child board, and I have a MMB0 board on hand. I'd like to mount my child board to MMB0 interface port and using your ADCpro software as a evaluation software.
I worry ADCPro or MMB0 DSP software maybe read the 256K EEPROM content when it startup, and refuse to continue to work if it cannot read out the correct data from 256K EEPROM on the child board.
Could you tell me whether it possible to bypass the EEPROM checking?
If not, could you provide the EEPROM data content, so I can implement my EEPROM on my child board.
Part Number:TMS320C6657
Hi We observing the below error when we connect JTAG and configure as SPI boot mode. We don't see this issue if we configure DSP in NO BOOT mode. We replaced the Flash IC with the new one but the issue still persists. We also checked for any power supply drop. All the power supplies are stable and no drop in voltage. Additional information: We are seeing this issue only in few boards. Please let me know what could be the issue.
Error connecting to the target: (Error -1143 @ 0x0) Device core was hung. The debugger has forced the device to a ready state and recovered debug control, but your application's state is now corrupt. You should have limited access to memory and registers, but you may need to reset the device to debug further.

Which model I need to use, Model_172, Model_173, Model_174 or Model_175?
Model_172 I/O,3.3V,40D CLASS MODE FAST MODE,IND,10 PERCENT%,BC40D_H_10P_!SC1_3P3
Model_173 I/O,3.3V,40C CLASS MODE SLOW MODE,IND,10 PERCENT%,BC40D_H_10P_SC1_3P3
Model_174 I/O,3.3V,40D CLASS MODE FAST MODE,IND,5 PERCENT%,BC40D_H_5P_!SC1_3P3
Model_175 I/O,3.3V,40C CLASS MODE SLOW MODE,IND,5 PERCENT%,BC40D_H_5P_SC1_3P3
What is the difference between the models?
Thank you ,

Part Number:LMH0344
Hello,
In the AC electrical characteristics table, Note 6 implies 3 parts in parallel (8.2 NH, 0.5 pF, and 75 ohms) on the SD344 evaluation board.
The typical application Figure 3 drawings shows just a 3.9 nH in parallel with the 75 ohms.
The layout example appears to show 5 parts on the input (2 in parallel, 2 in series to GND, and then the 1.0 uF cap to the input)
The different sections of the datasheet appear to contradict.
Can you supply the SD344 eval board schematics and layout to clarify?
Thanks,
Jordan
