Part Number: DS125DF1610

Hi,
I am able to generate PRBS signal out of QUAD1 TX channels (QUAD1 input is ref clock). I am trying to get PRBS checker working out of QUAD0 channels.
I can't get it to work, even CDR is not locked.
Please help me set PRBS checker setting correctly.

Thanks,

Kilhun


LM5116-12EVAL: LM5116 Change EVAL Board to Input: 40-64V - Output:34V/12A

Part Number: LM5116-12EVAL

Hello,

I got a LM5116-12VEVAL/NOPB Board (see attachments) for testing. I used the Webench Tool to create a circuit for my application: Input: 40-64V - Output: 34V/12A (see attachments).

To reach my designated output voltage, I only changed the RFB2/Rfbb resistor from 10.7kOhm to 33kOhm (RFB1 is still 1,21kOhm). But when I turn on the voltage, the LM5116 breaks.

I know that there are more differences between the Board and the Webench Design like the Input&Output capacitors but I hoped that I could start by just changing the resistor.

Could you help me getting my application started?

Many thanks in advance,

Marcel

Hi Ti team,

I am going to use DP83867IR Ethernet PHY IC in my project and I have found Modular connector 1-2301994-1 and 6-2301994-1 of TE Connectivity. Please let me know about the compatibility of both connector with the PHY IC.

LP5009: LP50xx Driving external mosfets in 12bit PWM resolution

$

Part Number: LP5009

I am willing to use LP5009 as I2C programmable PWM controller with these key parameters:

1) Open drain 2Amp outputs, is the proposed schematic valid?

2) 3-phase channels to reduce current spikes. Does LP5009 outputs "OUT0/1/2" are working in 3-phase mode? Asking this because chapter 8.3.1.4 of "SLVSEH2A rev 2019 July" mentions "LED 0 .. 11", not OUT 0..11 (1 RGB LED occupies 3 output channels OUT0..2, could be a typo mistake if copied from LP5036 part's datasheet..);

2) 12 bit resolution. How to operate with LED0_BRIGHTNESS and OUT0_COLOR registers to get 12 bit resolution accuracy for single output? For example, I would like to get 12bit value 0xBCD (0b101111001101) in the output. Should I write 0xBC to LED0_BRIGHTNESS register and 0xD0 to OUT0_COLOR register? 4 LSB's (0xD0 .. 0xDF) in OUT0_COLOR is automatically discarded?

  

ADS124S06: device not wake up after powerdown

$

Part Number: ADS124S06

Hi all,

we noticed a strange behaviour from ADS124S06. It seems that after a POWERDOWN command the device could not wake up anymore unless we send this command sequence:

STOP

WAKEUP

START

We want to powerdown the converter because we have two MCU that are reading the converter and the conversion result must be the same for both microcontrollers. So we think that we could obtain this behaviour if we powerdown the converter.

Are we missing something?

The converter is configured in this manner:

- pga bypassed

- continous conversions

- sample rate: 5 sps

- Reading from AIN4-AIN5

- Oscillator: internal

- Voltage reference: external (5Vd.c.)

BQ79606A-Q1: Problem waking it up for the first time

Part Number: BQ79606A-Q1

Dear TI experts,

We are working on building our own BMS and we have opted to use your BQ79606A-Q1 but we have some issues.

We have a BQ79606A-Q1 with the needed electronic components and connections made, and we am trying to make it balance 6 Li-ion cells also connected, but the problem appears when trying to wake it up in order to start balancing them. For the wake up we are sending from an arduino a low bit for 250 us (microseconds) and then a high bit for more than 30 us to the wake up pin (the 16th) as said in the datasheet.

Then, even we don't send anything else, the BQ should start running and doing his job, shouldn't it?

Are we doing something wrong at the process of waking it up? 

Best regards,

Alex

Dear everyone,

I have a question regarding the TIDEP-01012: I ordered the MMWCAS-RF-EVM and MMWCAS-DSP-EVM and was wondering: What is included in this package? Are the cables (power supply, data transfer) also included or do I need to order something separately?

Thank you and best regards,

Nominal Voltage: 3.7V
Charging voltage:4.2V

1. Using BQ24092 Charger how to limit the output voltage to 3.8V.

2. How much is the time taken to charge the battery using USB?

3.Any probelm is there, If I connect the load in parallel to the battery when the battery is charging through USB?

Please support on the above questions.

CCS/LAUNCHXL-CC2640R2: disable advertising by GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, .....) and end up stuck at while(abortLoop);

Part Number: LAUNCHXL-CC2640R2

Tool/software: Code Composer Studio

I am using the Simple_Peripheral example with blestack of CC2640R2 SDK v3.30.00.20, .

Following your (TI) suggestion,  I enable advertising with the following code:

static void SimplePeripheral_processStateChangeEvt(gaprole_States_t newState)
{

.....

switch ( newState )

{

case GAPROLE_STARTED:

uint8_t AdvertEnable = TRUE;

GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t),
&AdvertEnable);

.....

}

-------------------------------------------------------------------------

Then after advertising for 10 seconds, I try to disable advertising with the following code in my own Application Task:

uint8_t advertEnabled = FALSE; 

// Disable connectable advertising.
GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &advertEnabled);

-----------------------------------------------------------------------------

Then the program will end up stuck at the following while(abortLoop) :

ICall_abort(void)

{

if (abortLoop)
{
    while(abortLoop);
}

-------------------------------------------------------------------------------

I have no clue why it happened.  Please see the picture for reference:

Can anyone help ?

thank you.

SUBJECT : the TLV320ADC3140

 

Good day,

With over 64 audio analog ampifiers in a system on our workbench we are compulsing the TLV320ADC3140 literature ( datasheet).

We would like to integrate this audio analog-to-digital converter on a system for which we are usin ModelSim to simulate its performance and instantiation. For the purpose we wonder if you can provide us with VHDL or Verilog code.

The system will probably use DSP, FPGA or other similar resource (asic for instance)

How can you help.

With kind regards.

Hello,

I purchased a TIDE P0028 development board in order to use the industrial communication protocol.

However, I couldn't find any source code to start this programming in the CCS Code Explorer.

Am I able to get any examples so I can start doing some tests? At least the source code of the program that is recorded on the TIDE P0028?

Let me know your thoughts. Thank you very much.

Part Number: TCA9517A

Hi team,

My customer asked for I2C level shift/buffer solution but I can't find a suitable solution for them.

I need your suggestion. and below is customer's conditions.

1> They need pull-up resistor in both SCL/SDA pins

2> VOl output voltage level should be less than 0.38V because their companion part's VIL is lower

Thanks

Part Number: LM5050-1

Dear Sirs:

I need a chip as a prioritizer. There are a main power supply and batteries which are considered to supply the system. This chip should allow supplying by the main power supply unless its voltage goes under 18 volts, in this case I want this chip to be able to switch to batteries for supplying the system.

I have studied the chip “LM5050”. It’s quiet adequate for my purpose, but I couldn't understand how can I control the enabling of the chip. I understood that I need 2 chips separately, do I need any comparator in between? Can you suggest me some docs that could help me?

Thanks in advance

TMS320C6746: Can the 128 kB internal RAM safely be used in this device

$

Part Number: TMS320C6746

The 128 kB internal RAM is partly documented for the TMS320C6746 device, but is fully documented for the xx47 and xx48 devices. E.g. the TMS320C6746  is stated to have a total of 448 kB of onchip memory, the same as the xx47 and xx48 devices. We have also seen on real devices that this RAM is available and usable. Can we use this RAM safely for the TMS320C6746 device?

I tried to use one with SmartRF Studio 2.15.0 and got the following message:



I tried with an older SmartRF Studio 2.13.0 and got the following message:



Why is the message with the latest SmartRF Studio less meaningful ?

From the forum, i saw that Rev E was released in January 2019.

Why more than 5 months after the release of Rev E, there was still older revision sold ?
