General Description
The MX87 series are a family of PLL clock synthesizers with an integrated quartz crystal that achieves ultra-low phase jitter (<90 fs RMS 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 bination of LVPECL, LVDS, HCSL, or LVCMOS logic. For LVCMOS, however, only the true side of the channel is available.
The MX87 is packaged in a standard 48-lead TQFN.
