Ultra Low Jitter Clock Generators

The  any-frequency, any-output Si5391, Si5341, and Si5340 clock generators combine a wide-band PLL with proprietary MultiSynth fractional synthesizer technology to offer a versatile and ultra low jitter clock generator platform. The highly flexible architecture of the Silicon Labs generator is capable of synthesizing a wide range of integer and non-integer related frequencies up to 1028 MHz on up to 12 differential clock outputs while delivering sub-100-fs RMS phase jitter performance with 0 ppm error. Each of the clock outputs can be assigned its own format and output voltage, enabling the consolidation of multiple clock ICs and oscillators into a single device making it a true “clock tree on a chip.”
