Hi,
I am working on TDA5235. I want to configure it in FSK mode with 433MHz frequency. I am using TDA5235 Explorer for register configuration.
But I am not able to receive the correct data.
What are the main parameters I need to change to configure in FSK mode?
Or can you provide the configuration file for TDA5235 in FSK mode?
Please help.
Thanks and regards.

Hello, I'm using BGS16MN14, a kind of antenna switch with MIPI RFFE Interface.
Using my own MIPI protocol implementation, I can write at and read from most registers except REGISTER_0, which is for controlling the switch.
The data from REGISTER_0 using my MIPI Read shows only 0 even after I write other data using my MPI Write.
Is it normal operation, or is there any specific routines I have to follow?
Any help would be much appreciated. Show Less

Hi all,
I am working on the Hybrid-Kit for HybridPACK 2 Enhanced SIL and trying to follow an instruction sheet that comes in the package.
However, I am stuck at just the first step - Step 1.
Do you have any idea on what it means by HybridKit ECU and especially the OneEye software?
I couldn't seem to find it from Infineon's website and google does not show up any results as well.
Is anyone able to assist?
Thank you so much in advance.

Dear forum admin:
In recent days, the forum is often inaccessible, the error information returned is:
Error 330 (net::ERR_CONTENT_DECODING_FAILED)
I don't know if other users have the same problem.
This may be avoided by disable the gzip related feature in the forum settings. Please refer to these pages:

Hi!
I am implementing a 4-20mA current loop to my PIC. I have everything working.
I am measuring the distance away from an object.
When I hardcoded the distance as 300 the output voltage is 4V and when the distance is 12cm the output voltage is 0.8V.
These values are got because the current needs to be 200uA before it enters the current loop.
The current loop has a gain of 100, therefore giving 20mA on the output.
The resistor I use is 20K.
Here is the datasheet of my proximity sensor: http://www.kynix.com/uploadfiles/pdf8827/XTR115UA.pdf
(300cm) Current=420K=200uA×100=20mACurrent=420K=200uA×100=20mA
(12cm) Current=0.820K=40uA×100=4mACurrent=0.820K=40uA×100=4mA
The problem is I have to work out a formula for the duty cycle to get these values.
The formula I am using is D.C = 300×2.2+158=818300×2.2+158=818 which gives 4V but if i substitute 12 for 300 I get 184 which does not correspond to 0.8V which is what I need.
Can anyone help on this, if I am going about the wrong way or what way I need to approach this.
Thank you

I have a few questions:
1) Could we use an AC rated Contactor for DC switching? I have heard that typically the switching voltage a AC contactor can handle at DC for the same current is 10 times less. How do we arrive at this scaling factor of 10 times? Is it a practical figure or a properly calculated number?
Both of them are DC to DC converters. Both switching regulators and switching controllers can be obtained/configured in either buck (output voltage < input voltage), boost (output voltage > input voltage), or both topologies.
Does it mean that a contactor rated to switch 690V AC, 20A can handle 69V DC, 20A?
2) What is the fundamental limitation on switching DC vs AC. Is it just the longer sustained arc? If so, in case I use proper snubbers/ arc suppression circuits could I make use of AC rated contactors for DC?
A switching regulator works by taking small chunks of energy, bit by bit, from the input voltage source, and moving them to the output. This is accomplished with the help of an electrical switch and a controller which regulates the rate at which energy is transferred to the output (hence the term “switching regulator”).
The energy losses involved in moving chunks of energy around in this way are relatively small, and the result is that a switching regulator can typically have 85% efficiency. Since their efficiency is less dependent on input voltage, they can power useful loads from higher voltage sources.
Switch-mode regulators are used in devices like portable phones, video game platforms, robots, digital cameras, and your computer.
Switching regulators are complex circuits to design, and as a result they aren’t very popular with hobbyists. However Dimension Engineering creates switching regulators that are even easier to use than linear regulators, because they use the same 3 pin form factor, but don’t require any external capacitors.
3) Most relays and contactors are rated for resistive and moderately inductive loads. In case I am switching capacitive loads the switching becomes very bad and leads to welding of contacts. What is the best recommended approach to overcome this?
4) What is the fundamental difference between force guided relay and a contactor. Let's say both are at the same current rating.
Cheers! Show Less

Hello,
I'm highly interested in the new DSP310 atmospheric pressure sensor.
Can you - Infineon - please help me to
- get answers which are not provided in the data sheet (e.g. noise margin)
- get an idea of the price (single sample and quite low volumes)
- kindly ask for a sample
I have developed an aeromedelling altimeter/variometer employing an MS5611 with an elaborate noise filter which features
- quite good filtering and
- really useable filtering speed.
Of course I'm curious if this can be improved with the new DSP360.
Kind regards
