GENERAL DESCRIPTION The AD9516-0 generates up to fourteen output clocks from a single input reference frequency. Integrated on chip is a complete PLL with VCO, programmable dividers, adjustable delay blocks, and multiple output logic stages. Sub-picosecond jitter performance is maintained using on-chip 2.60 – 2.95 GHz VCO. The AD9516 also supports the use of an external VCO/VCXO/VCSO up to 2.4 GHz. FEATURES Low Broadband Jitter, < 500 Femtoseconds RMS On-Chip 2.60 GHz – 2.95 GHz VCO Low Phase Noise, Integer-N Frequency Synthesizer Digital or Analog PLL Lock Detect Programmable Delays in R and N path Supports Internal or External VCO Two Reference Clock Inputs, A and B Frequencies to 250 MHz On-Chip Reference Clock Monitors Auto and Manual Switchover, Holdover Up to 14 Low Jitter Clock Drivers Six LVPECL Outputs Operate to Max VCO Frequency Four/Eight LVDS/CMOS outputs run 1 GHz/250 MHz Programmable Dividers with Phase Offset Programmable Delay on Four Channels Serial Control Port 64-lead LFCSP package APPLICATIONS Low Jitter Clock Generation and Clock Distribution Wired and Wireless Infrastructure Base Stations, Optical Networks, Cable Head-Ends Instrumentation and Imaging Test Equipment, ATE Clean Clocks for ADCs, DACs, DDSs, DDCs, DUCs, MxFEs Clock Cleanup and Distribution for Line Cards
