We received this product as a sample from HiLetgo. A 7-pin breakout board is included with the breakout board There is a pretty good-looking header for soldering on to the board. The printed circuit board is very well constructed and clean. It is easy to see the connections. The chip has three output clocks that are available both on the header and on the solder terminals for use on PCBs SMA connectors mounted on the wall. The SMA connectors are available on Amazon, but I have yet to use them. Search for Si5351 on the Internet, or you can download several software libraries from the Internet. Using the Arduino IDE, you can choose the menu option Sketch | Include Library | Manage Libraries to search for a suitable library. Among the four libraries identified as "Etherkit Si5351", "Etherkit Si5352" is the easiest since it already includes the calculation of the PLL parameters. In the photo you can see the Si5351 board being connected to a D1 Mini and its Clock #0 group set to output.
There is nothing that can move it but a rock, a very The chip/board I selected is the basis for my drifty and ancient Atlas 210x to become a stable HFO. As it turns out, it has been a great choice. Controlled by an Arduino UNO, once the output frequency is set, it stays stable. The time period. There is only one issue I've had There is an actual 25 MHz crystal, not a nominal 25 MHz crystal. A bit of compensation has to be made in the choice of register values for a MHz of 00185. This device will be extremely pleased if it turns out to be reliable after I wire and package it permanently.
It is featured in a popular Ham radio magazine that uses this board as the source of power for a low-power transmitter. On these boards I built the transmitter and ran the code on the prototype board that I had ordered. The work I did was perfect. In the meantime, I have set up a permanent version of the system. With these three boards, I have completed a simple circuit. The next step is to construct a more complex circuit.
In the process of completing my electronics workbench, I was searching for a simple source of clock for various applications. The function generator isn't as good as a real function generator, but it's definitely enough to get by on In addition to testing the Si5351 chip, which can be used in other designs as a jellybean part, this board is an excellent way to use to test This is an outstanding board at this price. When I bought one a decade or two ago, it was unheard of that anyone could buy one at this price. It's like going from DC to VHF with this thing!.
These kinds of boards would have cost hundreds of dollars less than five years The size of the clock chips is the reason I purchased mine for my bench power supply, I'll post some updated pictures once I finish it. *** As others have stated, these are fairly flexible clock chips, I purchased mine to build a simple clock into my bench power supply. Initial testing with the trusty ol' 1054z indicates that the clock is accurate as far as the 1054z's frequency counter Item 1 (*1) The accuracy is 2 ppm.
There is no difference between this board and the one from "another seller. " Here you can find it Exactly the same parts and specifications are what I mean by identical This is a layout without any Adafruit logo, only the silkscreen is shown. The frequency of the crystal is 25. 002,518 MHz when this is used as a GPS disciplined oscillator.
Delivered quickly and in good condition.
