The Si5351 is an I2C-configurable clock generator ideal for replacing crystals, crystal oscillators, VCXOs, phase-locked loops (PLLs), and fanout buffers in cost-sensitive applications. Based on a PLL/VCXO + high-resolution MultiSynth fractional divider architecture, the Si5351 can generate any frequency up to 160 MHz on each output with 0 ppm error. The Si5351A generates up to 8 free-running clocks using an internal oscillator to replace crystals and crystal oscillators. The Si5351B adds an internal VCXO and provides the flexibility to replace both free-running and synchronous clocks. The Si5351B eliminates the need for more expensive, custom tunable crystals while providing operation over a wide tuning range. The Si5351C offers the same flexibility and synchronizes to an external reference clock (CLKIN).
