Giới thiệu Bo Mạch Phát Điện Đồng Hồ Si5351A I2C 25mhz 8khz Đến 160mhz
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 colour:purple Material:PC+ metal Package Contents: 1*Clock Generator Breakout Board 7*pin Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
