TMS320F28335: Can you kindly help share the Circuit schematic of TMS320F28335?

Part Number: TMS320F28335

Hi 

Can you kindly help share the Circuit schematic of TMS320F28335? Since I didn't find any schematic on the web.

The minimum system and peripheral circuit reference design of any TMS320F28335 is OK.

We need to have a reference, and then design the circuit board. The first version has a higher design success rate and can speed up our project progress.

Thank you.

Part Number: ADS131M04

I have checked on ADS131M04's data sheet. But it has SNR value only at gain = 1 and 64. So what is exact number of SNR @gain = 8 and how can I find this number?

LMZ31710: Relevance of AGND in LMZ31710 and TPSM84A22

$

Part Number: LMZ31710

Hi,
In the datasheet of LMZ31710, it is told not to connect AGND (analog ground) with PGND (common ground) because they are connected internal to the IC.

[1] What are the reasons for recommending not to connect AGND in PGND?

[2] Why are Radj and Rrt_clk referenced to ANGD and not to PGND?

I normally maintain one solid ground plane on layer 2 instead of dividing the ground planes. If I follow the recommended layout, I need to divide this solid ground plane. Having different grounds in a circuit board has its own set of problems; so I don't prefer to go to that path.

In the Zynq 7000 SoC EVM (zc-706; reference device - U98), AGND is routed as thick trace in layer 1, while underneath it in layer 2 is a solid PGND ground plane. In such a case, the EM fields of any signal in between Vadj - AGND connection and RT_CLK - AGND connection are contained within the traces on layer 1 and PGND ground below. This means that the PGND ground is referenced anyhow.

[3] Do you think the way it is routed in Zynq SoC okay?

[4] I have the exact same question for the routing of Radj between Vadj and AGND in the new power module TPSM84A22.

Thanks,
Binayak

LM74202-Q1: Can OUT pin be negative in shutdown ?

$

Part Number: LM74202-Q1

Hello,

When the LM74202 or LM76202 is in shutdown (/SHDN low) the power FETs are off.

Can the voltage on the OUT pin be negative (below GND) in this condition?

I would like to use the part as a current limited ideal diode and there is the possibility that the load will be a negative voltage (e.g. reverse battery) so I would shut down the part in that case.

Thanks for any help, Ken

[TDA4M] Network utilization in TIDL1.0 and Different run time between perf-sim and target.

$

Hi

I ran my CNN network using TIDL1.0 on target and host. I could check run time using performance simulator and target board. Actually, the run time on target is 4 times more than performance simulator.

In Execution Time for Networks of TIDL user guide, some networks have similar run time on target and perf-sim, and some have longer run time on target than perf-sim. It looks like some network was utilized well or some was not good.

I would like to know several things as below.

    1. Why is the run time different between perfsim and target ?

    2. What types of layer and network architecture can increase utilization ? 

    3. How can I see the utilization value in each layer ? ( you know, we could check the utilization value using perf-sim in TIDL0.9, but I can't see that in TIDL1.0 now.)

Best regards

Yongsig.

Part Number: TPS92561

Hi,

I am considering using an LED driver and power supply for use in LED lighting equipment for facilities.
The required power will be 50W to 200W.
Dimming is assumed to be triac dimming.
The TPS92561 device can do triac dimming, but is it possible to supply the power I need?

DS90UB954-Q1: The set of I2C rate

$

Part Number: DS90UB954-Q1

Hi,

The sentences below mean that the I2C rate of 954 is the host's rate , 953 and sensor's rate are depended on the settings for the proxy I2C master ,right?

I notice that 954 0x0A and 0x0B are the set as mentioned above. But 953 has two registers 0x0B  and 0x0C , they also have the same fuction .

I just don't know how to set the rate ,if I want 954 and 953 run in a same rate, for example, 400Khz.

Looking forward to your reply.

Part Number: CC1310

hi,

I am designing a Smart BMS (using BQ40Z80)  with sub-Ghz wireless connectivity. IC BQ40Z80 uses SMBus V1.1 protocol for communication, SMbus is new to me and on internet it seems I2c and SMbus both have similar characteristics.

my question is "what issues in communication i may face if CC1310 is used with BQ40Z80 or will it work together?"

Dear TI Team,

 

I have designed a Flybuck converter for 44Vin to 54Vin at 12Vout-iso, 1.2A using Webench. kindly find the design report in attachment, in order to get 12V output i have changed the values of rfbb and rfbt resistors , while operating at 44V initially the circuit works and shows the desired output voltage but after few cycles the switcher ic's pin (ie Vin and gnd) is getting shorted internally. kindly address me what possibly could be the reason. (Please visit the site to view this file)

Part Number: CC1310

I have used CC1310F128RGZT for 400 MHz application. I designed schematic referrening CC1310EM-SKY66115-4051 Rev2_0_x Reference Design Files. 

I am attaching my schematic too. My frequency of application is  400MHz.

I have checked output power at the point marked in RED. But the output power is 6 to 8 dBm instead of 14dBm from eval board LAUNCHXL-CC1310_1_3_0_Schematic. 

Can you help me to sort out this?
