This was very useful, thanks for sharing and the detailed talk through. I'm a beginner with this stuff and look forward to more of your excellent videos.
Thanks for an interesting and useful info! I've just been looking for the Arduino sketch information for my Si module which I found in my junk-box. I am planning to use it to improve my old crystal controlled transceiver. Subscribed! 73! Linas LY2H
i don't know if you are still with this oscilloscope, or about your conditions, but I just bought this oscilloscope: Dso2512g in Ali Express, and it just works fine. Not so expensive, 80usd.Great video!
I am surprised you got only 780 subs, did not check full channel contain to see if u upload regularly but according to this video I watched you deserve much more .
whats the maximum frequency output power? i need something that can do 8khz and 33khz at around 10W output power (or more) for making my own cable and fault locator
Good, informative video. Thanks for sharing it and the code sample. The device specification claims a square wave output across its range. The sine appearance might be due to scope bandwidth; do you see CLK0/1 both square wave at audio frequencies?
Essentially if this code can be fitted into the Nano that sits in the AT-20 or other generic radios you have a signal if Sinufied that can run the Rick Campbell SSB Phasing exciter from ARRL archives that I have detailed elsewhere on this board. I am suspicious about the OP CLK0 being a Sine wave but this is easily fixed via either of the two ccts I have detailed The GND gate FET schematic is of course more frequency sensitive to movement away from the design point . 73,s TEFidler Nouvelle Zelande.
Hold that thought Aniss.. I will send you a schematic to take a low level TTL signal and get three watts RF out of it on twenty metres. Essentially with minor tweeks what you show plus the existing chassis can be a three or four band CW QRP or even 10W transmitter for the work involved in making up a simple PCB and also adding a keyer cct and software to the Nano in the AT-20 or whatever brand of radio is used. TE Fidler
It's a mystery to me as well.. all those CLK0, 1 etc outputs are supposed to be the same. I can't see why it should be anything but a Square wave. TE Fidler

Enjoy man ! 73s
Sir pls reply

Thanks for sharing your project. How did you get a sine wave output? I am only able to get the si5351 to output square waves.

Thank you so much brother i really appreciate , i will be back ASAP!

Do you also have a solution for how to protect sensitive electronics from high-frequency ignitions of TIG welding machines?
Thanks for the information, we are waiting for new video 98

Sorry for late well . Its not about the oscilloscope bandwidth .its about synthesizing signals on higher frequency
how can we make sdr of freq 1ghz? do you know anything about it?
thanks.
Congrats ! Very nice and useful video. Thanks. 73 Denis F6CRP
Thanks !

Nice video mate 98
Thank you mazouna
just a question: why clock 0 looks like a "sinus" while clock 1 seems to be a square wave?
It's a mystery to me as well.. all those CLK0, 1 etc outputs are supposed to be the same. I can't see why it should be anything but a Square wave. TE Fidler
When it outputing higher frequency it goes more into sinusoidal because its digitizing ( higher resolution rate) more than lower frequencies
Can we sweep frequency from 10mhz to 50 mhz and return
Yes there is a sketch inside the si5351 library
Plz connect a display and a clickable potentiometer with it 🥺 plz make a dds vfo full
How You connected the output to sdr ? pls reply very important now 🙄🙄
The both i and q signals are connected to stereo line in
I ---->L
Q ---->R
(OR SWAP IT)
GND ----> GND
