Si5351C Overview
Description
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 200 MHz on each of its outputs with 0 ppm error.
Key Features
- Glitchless frequency changes ng/CMOS-Clock-Generators
- Generates up to eight non-integer- related frequencies from 2.5 kHz to 200 MHz
- I2C user definable configuration
- Separate voltage supply pins provide level translation
- Core VDD: 2.5 or 3.3 V
- Output VDDO: 1.8, 2.5, or 3.3 V
- Excellent PSRR eliminates external
- Exact frequency synthesis at each power supply filtering output (0 ppm error)
- Very low power consumption
- Highly linear VCXO
