AD9517-3ABCPZ

AD9517-3 is a 12-output clock generator with integrated 2GHz VCO. It provides a multi-output clock distribution function with sub picosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 1.75GHz to 2.25GHz. Optionally, an external VCO/VCXO of upto 2.4GHz can be used. 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 is used in applications 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.

• Low phase noise, phase-locked loop (PLL)
• 1 differential or 2 single-ended reference inputs, reference monitoring capability
• Automatic revertive and manual reference switchover/holdover modes
• Programmable delays in path to PFD, digital or analogue lock detect, selectable
• Additive output jitter is 225fs rms, channel-to-channel skew paired outputs of <lt/>10ps
• Each LVDS output can be reconfigured as two 250MHz CMOS outputs
• Automatic synchronization of all outputs on power-up
• Manual output synchronization available
• Operating temperature range from -40°C to +85°C
• Package style is 48-lead lead frame chip scale (LFCSP)
