SN65LVDS19: Off-Isolation Spec

$

Part Number:SN65LVDS19

Hi team,

Customer wants to use SN65LVDS19 in a differential CLK signal path, making use of enable pin to turn on/off signal path.

This will help them to improve isolation.

But they want to know the off-isolation performance of our chip.

Could you show the off-isolation data when dealing with 10MHz/125MHz/250MHz differential CLK signal?

Thank you!

Part Number:TL2845

Hi team,

My customer use PD controller +TL2845 in POE power supply, and use TL2845 as flyback, 

I want to know if TL2845 can be used as primary side feedback for isolated power? 

or do you have some reference design of isolated and non-isolated about this devices?

thank you very much

Part Number:TDA2

Tool/software: Linux

Hi Expert,

I'm running Linux Vision SDK v03.02.00(4.4.84) on TDA2Ex.

run usecase: "chains_lvdsVipMultiCam_Sgx3Dsrv"

Can get the load of DSP1 and M4-2 as the picture below.

But the value of A15 is fixed, How to modify?

grpxSrcLink_svStandalone_layout.c
Int32 GrpxSrcLink_displaySurroundViewStandaloneStats(GrpxSrcLink_Obj *pObj)

Delete line 449, 450,
The value of A15 is 0.

Could you please give some suggestion here?

Thanks in advance.

Hi.

Application note for TUSB211 physically shortens D1P/D1N to D2P/D2N.

I fail to understand how the device works.

Signal can't pass through the device if it is shortened.

Please clarify

CCS/TMS320F28379D: F28337xD Example Code Stuck in F2837xD_SysCtrl command

Part Number:TMS320F28379D

Tool/software: Code Composer Studio

Hello everyone,

I'm having some problems while running the example timed_led_blink_cpu01 from controlsuite.

I've made some modifications to the original project, like adding to my code an .cmd file (2837x_RAM_lnk_cpu1.cmd) and modified the length of RAMGS4 from 0x001000 to 0x12000, and renamed it to LOG.

After that I've commented the other RAMGS lines until the RAMGS15.

I'm also adding in the LEDBLINK.c code, inside the cpu_timer0_isr void the function logger(), and including the logger files .h and .asm to the project.

When I build the project It doesn't show any error, but it does not work since apparently the code is stuck on the F2837xD_SysCtrl.c code in the 556 line: while(ClkCfgRegs.SYSPLLSTS.bit.LOCKS != 1)

Does anyone knows how to fix and/or why this problem is occuring ?

Thanks in advance,


Izabela.

BQ24650: Correct value of R2 in Typical application diagram

Part Number:BQ24650

Hi,             

  I am using BQ24650 Ic for charging the 3.7V, 6600 mAh battery and the input supply form the solar panel is 12V, 30W. I want to charge the battery as well as want to supply the load circuit (Application circuit) of up to 4.2V, How can i make the circuit for this ?

I have changed the value of R2 which was 499k to 79.19k for 3.7V of battery (PFA). For the application circuit (from direct solar panel : Vsys) supply should i connect it to parallel to battery or connect a 4.2V LDO.

Part Number:TIDA-00554

Dear Sir,

My customer read the photodetector value in the lamp. The value is not consistence with different board.

Test flow:

-input the fixed voltage(0.45V) on sense_1 as channel 2 in waveform below.

-read the photodiode value through NIRSCAN NANO GUI. And the data is different with board. it seems there is 20% deviation with correct value. And the data changes with board.

Can you explain how it reads the sensor data?

How accurate is the result and how to improve it?

BR,

frank

Part Number:ADC32RF80

Hi

I used TSW40RF80EVM with ADC32RF80 for the digitization of the pulses filled with sinuses 1005 M. Then ADC DDC mixed them with 1000M, decimated by 4 and filtered. TSW40rf80evm is connected to the TSW14J56. The sinuses has the equal initial phases, but the sinuses after  ADC (captured by High Speed Data Converter) has different phases. How can it be explained? And how can I make phases equal? Thanks.

BQ27750: Setting Term Smooth Time above 255 is not possible

Part Number:BQ27750

Dear TI-Team,

The max value of Term Smooth Time is 32767 seconds (according to the TRM).

In the bqStudio (1.3.80) it is not possible to change the parameter above 255. Setting the value to 256 will result in the value 0. 

How to change it, if a value above 255 is needed?

BR,

Patrick.

hi

a customer of mine is desinging w/ DP83822IF.

as they plan to use RMII interface, I was asked if the pull-up/-down resistors are required for Hardwar Bootstrap  Config. to set the RMII or if it these pins can be left HiZ and then set the config via software (PHY Reset Control Registers)...

I couldn't find it in datasheet, sorry for asking

thanks a lot in advance

Part Number:TMDS570LS31HDK

Tool/software: Code Composer Studio

Hi,

I'm interested in using a Virtula Machine for my development with CCS 5.5

I'll use the following  hardware:

Hercules Safety MCU, TMDS570LS31HDK

Emulator XDS200 USB JTAG (TMDSEMU200-U)

Software:

My host OS iis windows 10 Pro (64bit) with the latest updates.

On the virtual machine I'll install Windows 7 Pro (32/64 bit)

CCS Version: 5.5.0.00077

Which virtual machine software shall I use, in order to have maximum compatibility between my hardware and software?

Virtualbox or VMWare ?

In case of VMWare, Workstation 14 Pro or Workstation 14 Player should I use?

LM5122: LM5122 Transfer voltage issue

$

Part Number:LM5122

DC power supply setting is15V.
DC power supply would become 13V after power on, and the voltage and current would always jump.
The DC-DC Converter board turns out the voltage without boosting but the voltage drops to 10V.
LM5122 expected function: input 8V~20V, output 55V

Please help us to help clarify the problem.

Thank you....

CC2640R2F: BLE Mesh stack from TI

Part Number:CC2640R2F

Good day,

When can we expect to get the BLE mesh stack from TI? We currently use a TI Eddystone stack modified to allow connectability but it does not work great. We really need the TI stack ASAP as TI's competition (SiLabs) already have this and our products are falling behind without this functionality.

Please can you let me know about this?

Thank you,

Phillip Jacobs
