The MX87 series is a family of PLL clock generators with an integrated quartz crystal that achieves ultra-low phase jitter (<90 fsRMS typical). With up to six total outputs available and dividers on each output, this device can generate up to six different frequencies up to 875 MHz. Each output can be programmed to any combination of LVPECL, LVDS, HCSL, or LVCMOS logic. The MX87 is packaged in a standard 48-lead TQFN.
