Based on a PLL/VCXO + high resolution MultiSynth fractional dividerarchitecture, the Si5351 can generate any frequency up to 200 MHz on each ofits outputs with 0 ppm error. Three versions of the Si5351 are available to meet awide variety of applications. The Si5351A generates up to 8 free-running clocks using an internal oscillatorfor replacing crystals and crystal oscillators. The Si5351B adds an internalVCXO and provides the flexibility to replace both free-running clocks andsynchronous clocks.

Programmable rise/fall time control Glitchless frequency changes 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 power supply filtering Very low power consumption Adjustable output delay Available in three packages types:
