Description

The Si5351 is an I

C configurable clock generator that is ideally suited 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 200 MHz on each of its

outputs with 0 ppm error. Three versions of the Si5351 are available to meet a wide

variety of applications. The Si5351A generates up to 8 free-running clocks using an

internal oscillator for replacing crystals and crystal oscillators. The Si5351B adds an

internal VCXO and provides the flexibility to replace both free-running clocks and

synchronous clocks. It eliminates the need for higher cost, custom pullable crystals while

providing reliable operation over a wide tuning range. The Si5351C offers the same

flexibility but synchronizes to an external reference clock (CLKIN).
