Product Description
| Product Introduction The Si5351 is an I2C-configurable clock generator ideal for cost-sensitive applications replacing crystal oscillators, VCXOs, phase-locked loops (PLIs), and fanout buffers. Based on a PLL/VCO + high-resolution multi-synchronous fractional divider architecture, the Si5351 can generate any frequency up to 160 MHz with 0ppm error on each output. Three versions of the Si5351 address a wide range of applications. The Si5351A uses an internal oscillator designed to replace crystals and crystal oscillators. |
