CC1310: Radio directive (EU) testing report

$
0
0

Part Number:CC1310

To approve our product (Smart City light controller) according to the Radio Directive and apply the CE mark, we require a accredited testreport of the CC1310 chip, in reference design, according to ETSI / EN 300-220-2 to avoid repeating all of the radio specific testing.

Can TI provide this? And if yes who should we contact?


AM4376: GPIOs with mixed power supply

$

Part Number:AM4376

Hello

I'm using the AM376 processor in our design. My GPIO bank power supplies are mixed between 3.3VDC and 1.8VDC. Is it acceptable to have mixed I/O supplies for the GPIO banks and ignore the warnings as long as the GPIOs are used with logic levels that correspond to the supply voltage? The example below is from our design where the GPIO bank 0 is powered by BDDSHV9 (3.3V) BDDSHV3 (1.8V) and BDDSHV6 (3.3V). so I'm using GPIOs powered by the BDDSHV9 and BDDSHV6 at the 3.3VDC logic levels and the GPIOs powered by the BDDSHV3 at the 1.8VDC logic levels.

Part Number:AM5726

Tool/software: Code Composer Studio

Hello,

I am using Code Composer Studio version 7.4.0.00015 and I write code for a Sitara AM572x Coortex A15_0 core. I would like to instruct CCS (the tool-chain) to generate a so-called 'assembler listing file' as part of the compilation/linking process.

The following post is related but refers to older versions of CCS.

https://e2e.ti.com/support/tools/ccs/f/81/t/70365?Complete-Assembly-Listing-of-C-file-

Where can I find the setting in the properties that CCSv7 creates such a listing file?

Thanks,

Andreas

Part Number:SN74LVC1T45

Hi Team,

Just a simple question, I would like to know how much current drive capability this device has.

From below spec, I just want to understand, when VCCO is 5V for example, output current can be 32mA max correct? But how do I determine what VOH will be at 32mA?  

Customer wants to understand how to determine the drive capability of this device, or is this kind of logic device made for current drive purpose? thanks!

Any ideas why this chip only outputs 10.8ma total instead of the 120ma it should?

Part Number:TPS61177A

Hi Folks,

I'm working with the TPS61177A LED driver chip in a prototype and I'm running into a strange problem.  As the thread title above states the chip isn't putting out the expected current.  I'm measuring the current at the cathode side of D2. I'm not using the I2C features so the chip should default to 20ma per CSx right?  The voltage at D2 looks correct at 11.87V.  I'm not 100% certain that the chip is soldered correctly since this is a prototype that I soldered in our small reflow oven.

Does anything jump out as wrong?  I'd rather not re-do another board but if the schematic looks OK I guess that's the only thing left.

Thanks in advance,

Richard

TPS40057: TPS40057 UVLO Issue

$

Part Number:TPS40057

Hi Guys

A typical Buck application circuit, 10 to 36Vin, 3.3Vout 10A Iout MAX. Is the function of the UVLO of the TPS40057 related to the type of MOSFET? What I saw in the datasheet is irrelevant. But it is different in the actual measurement:
Before replacing mosfets, use PSMN8R5-60YS mosfet:
No load: UVLO protection point 8.2V; recovery point: 9.4V;
Full load 10A: consistent with no-load;
After replacing Mosfet, use FDMS86369 mosfet:
No load: UVLO protection point 8.5V; recovery point: 10.3V;
Full load: UVLO protection point 8.3V; recovery point: 8.9V;
The red part here shows a high difference, why is this happening when mosfet is different? How to explain? Where do I need to make changes to the schematic? The latter mosfet is currently used by mosfet. So far, we could only have the chance to change the mosfet. Customer required on components change except mosfet.
The schematic diagram is as follows: R10=220k ohm;

Your feedback are appreciated.

Thanks

MSP430F5528: MSP430F55xx Selecting XT1 and XT2 Oscillator for USB BSL Production Programming

$

Part Number:MSP430F5528

Greetings,

I'm designing a space-constrained board with the intention of using the MSP430F5528-IRGC. For the scope of the project, the MSP430F55xx is intended to emulate a MSC device to store configuration data from a (Windows) PC. After it disconnects from the USB port, its use from there is just to initialize an embedded system every time it's power-cycle'd and do nothing else (sleep?). To reduce footprint, I'm planning to use only the USB BSL to do production programming. Also if it helps, the current objectives are fast start-up time and 400kHz I2C master.

1. So upon using a fresh un-programmed chip, would it be possible to use an external oscillator leaving the XT1-output and XT2-output floating and feeding the external oscillators output into XT1-input and XT2-input? This is without touching the XT bypass settings.

2. Could I use just XT2 only, while leaving XT1 pins floating? I've read somewhere that XT1 is required but there's also a post here (MSP430G2xxx series I believe) that said that the microcontroller defaults to DCO if it can't detect XT1 on startup.

The current external oscillators I've been eyeing are the SiTime 1552 series (for XT1 if needed; 180-300ms startup time) and SiTime 1618 series for XT2 at 12MHz or 24MHz. Their "drive strength" seems to be configurable.

For the 1552 series, I saw this diagram illustrating their "nanodrive" function":

https://www.sitime.com/sites/default/files/gated/AN10037-SiT15xx-Optimized-Settings-for-32kHz-Inputs-MCUs.pdf

As for the XT2 (12/24 MHz) oscillator, I'm thinking I need to match its "drive strength" configuration to the MSP430F55xx microcontroller. I'm also thinking of looking for a 4MHz oscillator (or crystal) just in case there's too much of a hassle to wrestle with 12/24MHz.

Thanks for any help,

Scott

Part Number:TPS2HB16-Q1

Hi

Please would you be able to assist me with the following?

1. Do you have a more detailed datasheet for the TPS2HB16-Q1 device? The one available from TI is only a 10 page document which does not have many of the parameters and curves that I am looking for.

2. If a more detailed datasheet is not available, then will it be possible to at least know :

(i) the over current protection limit of the device

(ii) the maximum safe continuous current that could be drawn from the device (with the case held at 85 deg celcius

Thank you,

Lakshman

Part Number:SMARTRF06EBK

Hello,

I am working on cc2538, it uses ZNP as coordinator and i am looking to make ZNP coordinator as my OTA upgrade server.

By referring Z-stack OTA upgrade User Guide i didn't found anything related ZNP, though i read about the OTA dongle.

Do i need to port a part of OTA_Dongle code to my ZNP coordinator, if yes how?

Is there any guide available for this?

DS90UB960-Q1: Max coax cable length

$

Part Number:DS90UB960-Q1

Hi all,

I have following setup: IMX390 Sensor -> UB953-Q1 Serializer -> RG174 Coax cable -> DS90UB960-Q1 Deserializer -> TDA2p (ISP)

Sensor outputs FULL HD @ 60 fps. With short cable (< 2 m) everything is ok, but with longer cables (> 4 m) video is not stable, flickering happens.

My questions are:

1. Can this be solved by changing values in AEQ registers 0xD2-0xD5. If yes, can you help me with that? I tried to set ADAPTIVE_EQ_FLOOR_VALUE to different values, but there are no changes.

2. Is the length determined only by cable quality and total insertion loss of all components in the signal path? What is correct formula for max cable length calculation for this setup?

3. Can something else cause this kind of problems?

Best Regards,

Stefan.

LM5166: 100% mode transition, COT operation

$

Part Number:LM5166

Hi,

Please describe operation during the transition to 100% duty cycle mode while in COT operation. Is there a minimum OFF time specification when in COT mode?

We are seeing Vout fall during pulse loading with reduced Vin without any extension of the COT on-time. Specified Vin for this converter is 30V-42V, Vout=24V, f=200KHz. With 32V in, measured off time is 300ns during the pulse load, efficiency ~80%.

It looks to me like the converter is saturating with a min off time limitation, but there isn't a spec for that parameter. Referring to the below trace, the light blue is the Vout during pulse load. You can see that steady state Vout decreases during pulse load by about 50mV. When Vin is increased, this offset goes away and the steady state Vout during light and heavy load is the same. We realize that this 50mV is small compared to the 24V output, but we need to understand the cause of this phenomenon.

Thanks.

TPS23523: TPS23523 datasheet spec, what is GATE=Hi

Part Number:TPS23523

Hi Team,

While testing startup waveforms of our EVM, I found 23523 will enter normal operation mode when

When I test GATE2 as well as GATE. It has been mentioned that it is after GATE reaches 7.5V that GATE2 starts to rise. Thereafter, GATE will start to rise steeply with ~1ms delay.

In addition, it is really apparent that BGATE has a lot of drops during start up and quantities of drops are related to VIN.

(1)Please kindly give a comment on that 1ms delay between GATE2 reaches 15V and GATE reaches 15V. Does GATE=7.5V means GATE=Hi?

(2)Please kindly give a comment on BGATE delay during start up.

Thank you very much!

TSB81BA3E: Are all ERRATA issues in SLLZ015C resolved with the TSB81BA3E silicon

Part Number:TSB81BA3E

Good day,

We experience random bus resets, the moment you connect a "leave" node to a network of 30 nodes configured for 1394b ports. A "leave" node is explained below:

The moment you configure the link connected to the leave node to be a 1394A port, the resets disappear. Reading the ERRATA LLZ015C the BOSS arbitration was also solved with this resolution. This make us think this problem are also related to the BOSS arbitration.

Do you have any evidence that this problem was solved with TSB81BA3E silicon or might it still be present? Any suggestion or work around you can suggest?

Regards,

Johan
