Hot-selling and scarce AD9516-3BCPZ 14-Output Clock Generator QFN64 spot stock

Product Descriptions

The AD9516-3 ¹ provides a multi-output clock distributionfunction with subpicosecond jitter performance, along with an onchip PLL and VCO.The on-chip VCO tunes from 1.75 GHz to2.25 GHz . Optionally, an external VCO/VCXO of up to 2.4 GHzcan be used 

The AD9516-3 emphasizes low jitter and phase noise tomaximize data converter performance,and it can benefit otherapplications with demanding phase noise and jitter requirements .

The AD9516-3 features six LVPECL outputs (in three pairs)and four LVDS outputs (in two pairs). Each LVDS output canbe reconfigured as two CMOS outputs . The LVPECL outputsoperate to 1.6 GHz, the LVDS outputs operate to 800 MHz, andthe CMOS outputs operate to 250 MHz .
