Si5391 Data Sheet Ultra Low-Jitter, 12-Output, Any-Frequency, Any-Output Clock Generator The any-frequency, any-output Si5391 clock generators combine a wide-band PLL with proprietary MultiSynth™ fractional synthesizer technology to offer a versatile and high performance clock generator platform. This highly flexible architecture is capable of synthesizing a wide range of integer and non-integer related frequencies up to 1 GHz on 12 differential clock outputs while delivering sub-100 fs rms phase jitter performance optimized for 100G/200G/400G applications. Each of the clock outputs can be assigned its own format and output voltage enabling the Si5391 to replace multiple clock ICs and oscillators with a single device making it a true "clock tree on a chip.
