AD9517-2ABCPZ

GENERAL DESCRIPTION

The AD9517-31 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 1.75 GHz to 2.25 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 1.75 GHz to 2.25 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
