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 in 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 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. 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 Exact frequency synthesis at each output (0 ppm error) Highly linear VCXO clock input (CLKIN) Low output period jitter: 100 ps pp Configurable spread spectrum able at each output Operates from a low-cost, fixed frequency crystal: 25 or 27 MHz Supports static phase offset Programmable rise/fall time control Glitchless frequency changes Separate voltage supply pins: Core VDD: 2.5 or 3.3 V Output VDDO: 1.8, 2.5, or 3.3 V Excellent PSRR eliminates external power supply filtering Very low power consumption Adjustable output-output delay PCIE Gen 1 compliant Supports HCSL compatible swing HDTV, DVD/Blu-ray, set-top box Audio/video equipment, gaming Printers, scanners, projectors Residential gateways Networking/communication Servers, storage XO replacement Material: PCB Colour: Fuchsia
