Page 1 2 So far as I know we have no offering on this. What do you want to use it for? Gc40116, i’m having some problems with the CC This probelm was solved by adding a current limit controller to the CC power input.
Part used was TPS The current limit controller interupts power for 80 ms which resets the latch up condition. Note that putting ESD protection on the antenna lead is very problematic.
Anything you add will either distort the RF signal or reduce power fatasheet. Parts with higher voltage thresholds do nothing to stop the C from going into latch up. How could I get the manual of the CebalDll.

As mentioned in the GC datasheet, the polyphase filter implementation used for the wideband downconvert mode, does not have as much adjacent channel rejection. The decimate by 8 example, provides for the widest bandwidth. As the filter bandwidth is increased the adjacent stop band rejection of the CFIR is lowered. Custom GC Ultra wide band filter taps are not normally provided. I have included filter taps developed for previous GC projects, you can select and test from the archive for the UW mode.
Any additional filter development has to be approved by Ken Chan kenchan ti. I got a DK-ccz,but i didn’t find any documents about SmartRF05bb,do you have any one ,you can email me.
From this “But if it’s a break between the packets you will need a long preamble to settle the receiver bit and byte slicer, frequency track since between the packets the receiver will start tracking noise.

There are several sync sources and logic sections within the GC Reviewing the problems you have noted:. The accumulated phase value will be different from each GC if they are released from NCO accumulator sync at different clock cycles. In our application, we are operating at MHz input sampling frequency. We have chosen wideband mode of DDC and decimation factor set to As long as the power doesn’t exceed the range very much dattasheet it is ok – It would be recommended to use something close to 0 dBm into the FB port.
This will get you up an running without any need for external PAs or couplers. This is just a GUI issue. The clock design tool blindly designs for the loop bandwidth for the optimal jitter, disregarding fractional spurs and disregarding the fact that the capacitors will be small.
So I recommend NOT dataaheet the “Recommend Design and Calculate” and instead just specify your loop bandwidht and phase margin and just calculate with this. The loop bandwidth and phase margin you pick will probably be lower than what the tool designs. We are working on a new tool now, but until then, you can use the tool, but be cautions of this C3 value and don’t design as wide loop bandwidths as it recommends.
Also, try higher phase detector frequencies and higher charge pump currents to get the C3 value higher. Are you the publisher? Claim or contact us about this channel. Embed this content in your HTML.

Hi, looks like nothing is moving on this topic, is anyone working on this? Power meter in GC Manual of the library “CebalDll. Hello As mentioned in the GC datasheet, the polyphase filter implementation used for the wideband downconvert mode, does not have as much adjacent channel rejection. Hi Adam, OK, thanks a lot for your answer.
Could you tell me if you can send me the Touchstone file for the TRF? I look forward to hearing from you.
Cannot datashet with SmartRf05bb via usb cable and SmartRf05bb. I very appreciate it. Hello, There are several sync sources and logic sections within the GC Reviewing the problems you have noted: GC – wideband mode – Decimation.
Hello In our application, we are operating at MHz input sampling frequency. Could you please provide coefficients for the above requirement?
Hi Tom, As long as the power doesn’t exceed the range very much then it is ok – It would be recommended to use something close to 0 dBm into the FB port. Software issue with the LMX Codeloader program. Frank, This is just a GUI issue. Conflicting result for LMX software tools.
Frank, No, you are not missing anything and you are correct to observe this. Browse the Latest Snapshot. Browsing All Articles Articles.
