Hello Guys
To repair an agilent IO logger card we need 5 pieces of TTL bus switch "SN74CBTK32245ZKER".
I cant find it on the TI homepage, but you can buy it in the Internet. (only whole VPEs :()
Do you know where i can order 5 pieces of this IC?
best regards
Tom
Part Number: ADS2807
Hello,
I wanted to stimulate an anti aliasing filter before ADS2807,
Can I get a spice model for this ADC or is it fine if I stimulate the input to ADC as a 1.25M resistor in parallel with 3pF capacitor?
Can the transformer circuit at the input of ADS2807 Eval board used for isolating RF ground of the signal and Analog ground of my board?
Do you have any application note or circuit describing Isolation and anti aliasing for ADS2807.
Thanks and regards,
George.
Part Number: LM3445EVM-695
Dear all：
1，We have a line lamp project requirement, and we are going to use LM3445 to do it.I have seen TI's lm3445evm-695, and I think this circuit is relatively complex. Can you explain the functions of each circuit in the DEMO (the position of the red box is drawn)?
2，The capacitance of lm3445evm-695 is 22uF.If the grain filling capacitance increases, does it affect the output?There is a formula for the relationship between capacitance and output voltage and current
3，The output dimming line lamp power is not the same (such as: a total of three line lamps in parallel, the output voltage is 42V, the current is 160MA, 320MA, 480mA), what should LM3445 do to ensure the dimming depth of three lamps consistent？
Thank you！
Part Number: TMS320F28075
Hi team,
I am supporting my customer using F28075 SDFM to encode AMC1303 manchester input.
However, I noticed the manchester logic is inverted. On C2000, a rise jump is 0, a falling jump is 1. However a rise jump is 1, a falling jump is 0.
Can we config to invert the GPIO when it is used as SD input?
Besides, the timing logic is also inverted on C2000 and our AMC devices. For example, on AMC1303 the data flips on rising clock edge, but C2000 requires 5ns after the rising edge. Which means we must select a device with slower rising speed.
I not sure why we designed SDFM with this logic? Is there a special consideration?
Part Number: DS90UH949-Q1
Hi
Some question about the CEC
1. What will DS90UH949 do when receiving CEC command from HDMI connector ? (we got some question like will DS90UH949-Q1 decode the CEC command ? How will DS90UH949-Q1 react to CEC command ? )
2. How to implement CEC function using DS90UH949-Q1 ?
2. Can we at the DS90UH940 side control / Access DS90UH949 CEC either to get the CEC command result or send CEC command ?
Part Number: DP83867CR
What type of twinned RJ-45 is better to choose if we plan to use 2 pcs of DP83867CR in one board? Do you have any recomendations? Are there any specific requirments for the choosing RJ connectors?
Thanks in advance!
Part Number: TMDSCNCD28379D
Hi all,
I would like to know it's possible to replace the controlCARDs between TMDSCNCD28379D and TMDSCNCD280049C in general. Are there any concerns to do that? Also can you tell me what are the differences between 28379 and 28377? Why did you name the file indicating the pinout "TMDSCNCD28377D_180cCARD_pinout_R1_3.pdf"?

Part Number: LM34936EVM
Hello team!
Where can I get the Schematic & PCB data for LM34936EVM?
If there's no file on the website, would you mind sending those data personally?
I would like to check those files thought Altium so that I can explain this device to the customer.
Thank you,

Part Number: IWR1443BOOST
Hi,
Some time ago I bought the IWR1443BOOST evaluation board.
A month or so ago I started playing with it, and I have the demo setup working.
Im now trying to define new configs. And Im having some difficulty there.
I did some reading and it appears the the MMWAVE DEV package is needed as well for this.
However there is also the sensing estimation website that produces the JSON, which is not the .cfg file that is needed
My questions:
1) the MMWAVE DEV pack seems not to be sold anymore. Is that correct? What is now the best way to find configurations?
2)in general, what is the best way to set up new configurations?
3) the documentation that goes with the firmware has information about creating configs. Is there other information available?
4) is there a config repository that contains demo configurations?
For example: gesture recognition, hart beat detection, detecting an object within 5m, detecting an object within 100m etc.?
Apologies when somebody else also asked these question; I did not find it in my search.
Best regards,
Maurice
Part Number: BQ76PL455A-Q1
Tool/software: Code Composer Studio
Hello everyone,
I am wondering that whether I can program microcontroller in BQ76PL455A-Q1 Evaluation Board or not. If I can program it, How can I do it? ıs there any document regarding with this issue? And Can I program it on C/C++ level or Do I need to program it on register level?
Also I want to learn communicaton between microprocessor and BQ76PL455A-Q1 chip. Does BQ76PL455A-Q1 chip send measued voltage current values automatically on preset settings or do we need to configure it ?
Thanks.

Tks!
Part Number: UCD90320
Hi there,
In my project, our customer would like to use UCD90320 judge if input voltage (PVNN_PCH_AUX) for PCH is normal or not?
Power: PVNN_PCH_AUX is generate from TI TPS51518 chip and TPS51518 communicate with PCH by VID signals.
TPS51518 provide 4 different voltage (0.85V,0.9V,0.95V,1.0V) to PCH by VID setting accordingly.
We intend to connect PCH VID signal to UCD90320 GPI pin so that UCD90320 know what PVNN_PCH_AUX voltage level should be.
UCD90320 can check PVNN_PCH_AUX is normal or not?
PVNN_PCH_AUX is connect to UCD AMON pin, Intel PCH VID connect to UCD DMON as GPI purpose.
Please feedback the connection is correct or not.
Thank you.

Part Number: TPS65987D
Hi, everyone,
Now we noticed this problem, when we use "Samsung Travel adapter (EP-TA845)."
Its PDOs are:
5V==3A
9V==3A
15V==3A
20V==2.25A
(PPS) 3.3-11.0V==4.05A
(PPS) 3.3-16.0V==2.8A
(PPS) 3.3-21.0V==2.1A
As our products (PCs) are designed so that they don't support PPS,
when we attached its adapter,
TPS65987DDH should request 20V==2.25A (i.e. ask for max).
But when Samsung adaptor send SouceCap, TPS65987DDH do soft reset...
Why is it ?
We'll attach PD analyzer data caption
and send data to your colleague Yone-san.
And our base FW ver. is F707.10.05 & F707.10.06.

How can I use the phase value to calculate the angle in RVDT?
Part Number: TPS65987D
Hi ：
We first made the TYPE-C solution, and now it is found that the PP-HV2 of the TPS65987D pulls the power supply 5V（ Aways power ）low at power-on.Is the software setting problem causing chip protection? Please help check if our software configuration is OK?The application of our TYPE-C is mainly the switching of USB/DP signals. In DP mode, it needs to output 5V power for DP monitor.Attachment is schematic and PP HV configuration table.(Please visit the site to view this file)
Part Number: DAC43608
Hi Expert
My customer need to consider about restart method when I2C communication error.
For example, LM73(Temp sensor) has timeout function for I2C. So, customer plan to use this function.
Do you have any good ideas for the restart method with DAC43608 when I2C communication error?
Software Reset is a reset method that assumes I2C communication is possible. they cannot use this.
Thanks
