About this item

  • The chip has a precise 25MHz crystal reference and an internal PLL and divider.
  • It can generate almost any frequency, from <8KHz to 150+ MHz.
  • The Si5351 is an I2C configurable clock generator ideal for replacing crystals, crystal oscillators, VCXOs, phase-locked loops (PLL) and fan-out buffers in cost-sensitive applications.
  • It uses an onboard precision clock to drive multiple PLL and clock dividers through I2C instructions. The output is 3Vpp, via a breadboard-fit connector or, for RF work, via the optional SMA connector.


Never hunt around for another crystal again, with the Si5351A clock generator breakout This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from

All three developed a problem withing a week of putting into service. One stopped all outputs, the other two put out wrong frequencies in certain ranges. Do yourself a favor and spend the extra money for an Adfafruit module...

These are incredibly handy for prototyping RF gear and are well-supported by Arudino.

j’avais commandé un deuxième lot de 3 car un ne fonctionnait pas dans le premier lot.. à ce prix, je reste content..à savoir..ne pas utiliser la librairie Si5351 de Adafruit et les exemples inclues..c’est trop compliqué inutilement..utiliser la librairie Si5351 de Etherkit, version 1.1.0 uniquement etcorriger l’exemple de calibration erroné (la fréquence corrigée n’estpas la fréquence demandée - le résultat du terminal).. utiliser votreSDR et placer la fréquence sur 30.000 Mhz, il y a une station de référencequi émet sur cette fréquence.. ajuster votre "PPM Correction" pour coïnciderle SDR avec cette station qui émet en continu en onde pure.. maintenantque le SDR est calibré, mettre votre Si5153 sur 30 000 000 00 (30 Mhz avecles 1/100 de hz = 3000000000).. créer un facteur de correction ainsi:facteur_de_correction = fréquence_demandée / fréquence_vue sur le SDRFreqOut = Freq * facteur_de_correction;il y a suffisamment d’exemples dans Etherkit pour manipuler le codepar la suite..attention, attendre un bon 10 minutes avant de calibrer car le Si5351 glisselentement en fréquence surtout pendant les premières minutes.. pour mapar, tous mes modules reçues ont une erreur de 140 à 150ppm en + (14 a 15khz sur100Mhz).. la datasheet du Si5351 indique 0ppm mais c’est par rapport à l’horloge d’entréeet cela concerne la puce uniquement (donc la qualité du cristal est ici déterminante)..bref, après des jours de recherches et avec la correction, ça fonctionne bien et c’est trèsamusant pour émettre en cw à faible puissance (environ 100mw)..

I like that the sma connectors are not presoldered. Usually I only need one output and I just leave the other ones off.

All three boards worked properly and the build quality is excellent.I am using this board in a 10M beacon transmitter as the VFO. It is controlled by a Raspberry Pi Pico.

I didn't measure every parameter of the Si5351, but the modules work as intended. No complaints.

Combined si5351, ESP8266, 128x64 OLED display and rotary encoder - made a very good, compact, and programmable frequency generator for several projects I work on.

Great product. Did not even have to adjust the accuracy of the board. Low jitter and excellent product.
