Our 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. With highly flexible architecture, the generators are 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 clock output 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.”
