The Si5351 is an I2C configurable clock generator that is ideally suited for replacing crystals, crystal oscillators, VCXOs, phase-locked (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 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 operation over a wide tuning range.The Si5351C offers the same flexibility synchronizes to an external reference clock (CLKIN).Functional Block Generates up to 8 non-integer-related frequencies from 8 kHz to 160 MHz I2C definable configurationExact frequency synthesis at each output (0 ppm error)Highly linear VCXOclock input (CLKIN)Low output period jitter: 100 ps ppConfigurable spread spectrum at each outputOperates from a low-cost, fixed frequency crystal: 25 or 27 MHzSupports static phase offsetProgrammable rise/ time controlGlitchless frequency changesSeparate voltage supply pins:Core : 2.5 or 3.3 VOutput VDDO: 1.8, 2.5, or 3.3 V PSRR eliminates external power supply filteringVery low power consumptionAdjustable output-output delayPCIE Gen 1 compliantSupports HCSL compatible swingHDTV, DVD/Blu-ray, set-top boxAudio/video equipment, gamingPrinters, scanners, projectorsResidential gatewaysNetworking/communicationServers, storageXO replacementcolour:purpleMaterial:PC+ metalPackage Contents:1*Clock Generator Breakout Board7*pinOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
