The AD9520-11 provides a multioutput clock distributionfunction with subpicosecond jitter performance, along with anon-chip PLL and VCO. The on-chip VCO tunes from 2.27 GHzto 2.65 GHz. An external 3.3 V/5 V VCO/VCXO of up to 2.4 GHzcan also be used.The AD9520 serial interface supports both SPI and I2C? ports. An in-package EEPROM can be programmed through the serial interface and store user-defined register settings for power-up and chip reset.The AD9520 features 12 LVPECL outputs in four groups. Anyof the 1.6 GHz LVPECL outputs can be reconfigured as two250 MHz CMOS outputsEach group of outputs has a divider that allows both the divideratio (from 1 to 32) and the phase (coarse delay) to be set.The AD9520 is available in a 64-lead LFCSP and can be operatedfrom a single 3.3 V supply. The external VCO can have anoperating voltage up to 5.5 V. A separate output driver powersupply can be from 2.375 V to 3.465 VThe AD9520 is specified for operation over the standard industrialrange of ?40?C to +85?C.1The AD9520 is used throughout this data sheet to refer to all the members of the AD9520 family. However, when AD9520-1 is used, it is referring to that specificmember of the AD9520 family.ApplicationsLow jitter, low phase noise clock distributionClock generation and translation for SONET, 10Ge, 10G FC, and other 10 Gbps protocolsForward error correction (G.710)Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEsHigh performance wireless transceiversATE and high performance instrumentationBroadband infrastructures
