Part Number:WL1837MOD

Is the WL1837MOD only a DFS Master device or also a DFS Slave device?

The datasheet as well as the "Wilink8 Feature Guide" only mention the AP / DFS master functionality. When looking at the FCC testing of the module, there is also testing for DFS slave (without Radar detection). Could you please clarify for me? Thank you.

Part Number:DCPA10505D

Hi Team,

My customers are using DCP010505D. There was nothing wrong.

They are considering replacing DCPA10505D for price reduction.

I know that DCPA10505D is better withstand voltage, can the device be replaced without problems?

I would like to know the point to be careful when replacing.

Also, please give me the same information about DCP010505 and DCPA10505 of single output.

Hi Experts,

I'm using SmartRF05EB and CC2530EM. Follow the sample application user's guide, I run the "7 Quick Start Guide".(Sample of light and switch)

The question is: After the commission, how can I know how many/which devices are binding with this Coordinator? I cannot find a screen menu tell me this. Is there any other way to know this?

Thanks.

SN74HC573A-Q1: Shared Pull-Down Resistor for Unused Channels

Part Number:SN74HC573A-Q1

Hi,

I am supporting customer for their design w TI SN74HC573A-Q1. It is a common knowledge that all unused input terminal should be tied to VCC or GND for determined state in each channel. Is it OK to pull down all the unused D terminals to GND with a single resistor?

I think this would work if all the D inputs are pure CMOS gate inside and no current is sourcing out from the D terminals. 

Thanks for your help!

Hi

I have a question here if write a code like below directly(Not in MEMORY or SECTIONS):

__RAM_Start = 0x2000; /* RAM Start */

1:Does that mean I defined a pointer that named "__RAM_Start " that point to address "0x2000" ?(Which document  and which part I can refer to? The more detail the better)

2:Does the "__" have any special meaning here? And how about "_" ?

The using condition you can refer to the my application cmd file

Part Number:AM6548

Hello,

I would like you to confirm through put of PRU_SS.

I'm trying to check through put of network performance by using Linux SDK and AM654x GPEVM.

Here are result of iperf.

Above is result of eth0. This is expected result (Similar as benchmark.)

Above are result of eth1(PRU_SS) and eth2(PRU_SS).

The results are approx 160 Mbps. It seems too narrow.

So, Could you confirm whether this is expected result or not ?

SDK version which I use is SDK 05.02.00.10.

1、Smart Studio  2.12.0 has no the options of Proprietary Radio Mode, which is the version supported Proprietary Radio Mode for CC2652R? if no , do you have documentation on how to manually modify these      parameters?
2、Are the configuration parameters above set correctly? Especially .modulation.deviation 、 .symbolRate.preScale、  .symbolRate.rateWord  and  .rxBw ？
3、Because of the absent eww file for ti\tirtos_cc13xx_cc26xx_2_21_01_08\examples\IAR,  How do IAR IDE use these routines?

TPS659037: External crystal spec

Part Number:TPS659037

Hi team,

Can the customer use following crystal with relaxed spec to some extent for PMIC? PMIC doesn't require 16MHz crystal for the operation, so I assume relaxed spec crystal will be used for PMIC, if accurate external clock output is NOT required. 

<16MHz crystal spec>

±50 ppm at -40C to 105C

The customer commented they just use  power supplies of PMIC and I2C, don't use  ADC, RTC. 

Thank you for your support. 

Best regards,

Hi Engineers

The 12V power supply will involve the protection of hot plug, and the main purpose of using hot plug protection is to slow down the starting power supply and control the power off.

We also do not know whether it need with I2C interface and what kind of indicators to focus on parameters.

Please help to recommend the mainstream model.

Thank you!

I heard that some TI-Processors don’t allow changing some Bits within a byte-lane (e.g. least significant bit D0, D8…). Just for double check here, is it allowed with our used AM4376 to change/swap every Bit (D0-D7) (D8-D15) ?

Thanks in advance.

I have MATLAB v2017a

I installed SDK 1.2, MATLAB RUNTIME(9.2), CCS v8, Uniflahs v4.5 and industrial Toolbox 3.1.1

I successed Uniflash


As you can see in the picture, the load was successful. Then, I removed jumper(SOP2), connected jumper(SOP0)

I want to start GUI(Gesture Swipe)

I ran gettrue_recog_swipe_gui.exe in the instustrial file, but it did not work as shown below.


I'd appreciate it if you could tell me how to solve it.

WEBENCH® Tools/LMK03328: Request to add DF (Damping Factor) calculation result

Part Number:LMK03328

Tool/software: WEBENCH® Design Tools

Hi Team,

Why doesn't the WEBENCH Clock Architect result not have the "Damping Factor" information ?

It would be helpful if the WEBENCH result would also have  DF value to understand better PLL stability.

Is it possible to predicate that the PLL is stable without considering the DF, just by checking the phase margin ?

On of other TI clock software shows DF result.

Best Regards,

Kawai
