The SM806xxx is a PLL clock generator that achieves ultra-low phase jitter (78 fs 12KHz to 20 MHz). With six total outputs and dividers on each output, this device can generate six different frequencies up to 875 MHz, from a low-cost quartz crystal or a reference clock input. Each of the six outputs can be independently programmed to LVPECL, LVDS, HCSL.

The SM806xxx is packaged in a 48-pin VQFN with up to six outputs or a 24-pin VQFN with two outputs.
