The Si5351 is an I2C configurable clock generator that is ideally suited for replacing crystals,crystal oscillators,VCXOs,phase-locked loops (PLLs),and fanout buffers incost-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 errorThe 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. 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 configurationExact frequency synthesis at each output(0 ppm error)Highly linear VCXOclock input (CLKIN)Low output period jitter: 100 ps ppConfigurable spread spectrum able at each outputOperates from a low-cost,fixed frequency crystal: 25 or 27 MHzSupports static phase offsetProgrammable rise/fall time controlGlitchless frequency changesSeparate voltage supply pins: Core VDD: 2.5 or 3.3 VOutput VDDO: 1.8,2.5,or 3.3 VExcellent PSRR eliminates external supply filteringVery low consumptionAdjustable output-output delayPCIE Gen 1 compliantSupports HCSL compatible swingHDTV,DVD/Blu-ray,set-top boxAudio/video equipment,gamingPrinters,scanners,projectorsResidential gatewaysNetworking/communicationServers,storageXO replacementMaterial: PCBColour: FuchsiaPackage Contents: 1 x Clock Generator Breakout Board Only the above package content,other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
