Teyleten Robot Si5351A Si5351 5351 8KHz -160MHz High Frequency Signal Generator Breakout Board DC3.3-5V Square Wave Frequency Generator Board Module I2C for Arduino (3pcs)
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.
