<p>The Si5351 is an I2C configurable clock generator that is ideally suited for replacing crystals, crystal oscillators, VCXOs, phase-locked (PLLs), and fanout buffers in</p> <p>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 of its outputs with 0 ppm error</p> <p>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.The Si5351B eliminates the need for higher cost, custom pullable crystals while providing reliable operation over a wide tuning range.</p> <p>The Si5351C offers the same flexibility but synchronizes to an external reference clock (CLKIN).Functional Block Diagram Generates up to 8 non-integer-related frequencies from 8 kHz to 160 MHz I2C user definable configuration</p> <p>Exact frequency synthesis at each output (0 ppm error)</p> <p>Highly linear VCXO</p> <p>clock input (CLKIN)</p> <p>Low output period jitter: 100 ps pp</p> <p>Configurable spread spectrum at each output</p> <p>Operates from a low-cost, fixed frequency crystal: 25 or 27 MHz</p> <p>Supports static phase offset</p> <p>Programmable rise\/fall time control</p> <p>Glitchless frequency changes</p> <p>Separate voltage supply pins:</p> <p>Core : 2.5 or 3.3 V</p> <p>Output VDDO: 1.8, 2.5, or 3.3 V</p> <p>Excellent PSRR eliminates external power supply filtering</p> <p>Very low power consumption</p> <p>Adjustable output-output delay</p> <p>PCIE compliant</p> <p>Supports HCSL compatible swing</p> <p>HDTV, DVD\/Blu-ray, set-top box</p> <p>Audio\/video equipment, gaming</p> <p>Printers, scanners, projectors</p> <p>Residential gateways</p> <p>Networking\/communication</p> <p>Servers, storage</p> <p>XO replacement</p> <p>colour:purple</p> <p>Material:PC+ metal</p> <p>Package Contents:</p> <p>1*Clock Generator Breakout Board</p> <p>7*pin</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
