GENERAL DESCRIPTION
The AD9517-11 provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 2.30 GHz to 2.65 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 2.30 GHz to 2.65 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
    2 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
    2 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
    Available in a 48-lead LFCSP
