GENERAL DESCRIPTION
The AD9516-41 provides a multi-output clock distribution function with subpicosecond jitter performance, along with an onchip PLL and VCO. The on-chip VCO tunes from 1.45 GHz to 1.80 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.

FEATURES
   Low phase noise, phase-locked loop (PLL)
      On-chip VCO tunes from 1.45 GHz to 1.80 GHz
      External VCO/VCXO to 2.4 GHz optional
      1 differential or 2 single-ended reference inputs
      Reference monitoring capability
      Automatic revertive and manual reference
         switchover/holdover modes
      Accepts LVPECL, LVDS, or CMOS references to 250 MHz
      Programmable delays in path to PFD
      Digital or analog lock detect, selectable
   6 pairs of 1.6 GHz LVPECL outputs
      Each output pair shares a 1-to-32 divider with coarse
         phase delay
      Additive output jitter: 225 fs rms
      Channel-to-channel skew paired outputs of <10 ps
   4 pairs of 800 MHz LVDS clock outputs
      Each output pair shares two cascaded 1-to-32 dividers
         with coarse phase delay
      Additive output jitter: 275 fs rms
      Fine delay adjust (Δt) on each LVDS output
      Each LVDS output can be reconfigured as two 250 MHz
         CMOS outputs
   Automatic synchronization of all outputs on power-up
   Manual output synchronization available
   64-lead LFCSP
