AD9516-3BCPZ

AD9516-3 is a 14-output clock generator with integrated 2GHz VCO. It provides a multi-output clock distribution function with sub pico second jitter performance, along with an on chip PLL and VCO. It emphasizes low jitter and phase noise to maximize data converter performance, and it can benefit other applications with demanding phase noise and jitter requirements. It features six LVPECL outputs (in three pairs) and four LVDS outputs (in two pairs). Each LVDS output can be reconfigured as two CMOS outputs. The LVPECL outputs operate to 1.6 GHz, the LVDS outputs operate to 800MHz, and the CMOS outputs operate to 250MHz. It is used in application such as low jitter, low phase noise clock distribution 10/40/100 Gb/sec networking line cards, including SONET, synchronous Ethernet, OTU2/3/4, forward error correction (G.710), clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs, high performance wireless transceivers, ATE and high performance instrumentation etc.

• External VCO/VCXO to 2.4GHz optional, 1 differential or 2 single-ended reference inputs
• Automatic revertive and manual reference switchover/holdover modes
• Programmable delays in path to PFD, digital or analogue lock detect, selectable
• Each output pair shares a 1-to-32 divider with coarse phase delay
• Automatic synchronization of all outputs on power-up
• Fine delay adjust (Δt) on each LVDS output
• Channel-to-channel skew paired outputs of 10ps
• Operating temperature is -40°C to +85°C
• Package style is 64-lead lead frame chip scale (LFCSP-VQ)
