The AD9517-4 provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 1.45 GHz to 1.80 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.The AD9517-4 emphasizes low jitter and phase noise to maximize data converter performance, and it can benefit other applications with demanding phase noise and jitter requirements.The AD9517-4 features four LVPECL outputs (in two 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 800 MHz, and the CMOS outputs operate to 250 MHz.For applications that require additional outputs, a crystal reference input, zero-delay, or EEPROM for automatic configuration at startup, the AD9520 and AD9522 are available. In addition, the AD9516 and AD9518 are similar to the AD9517 but have a different combination of outputs.Each pair of outputs has dividers that allow both the divide ratio and coarse delay (or phase) to be set. The range of division for the LVPECL outputs is 1 to 32. The LVDS/CMOS outputs allow a range of divisions up to a maximum of 1024.The AD9517-4 is available in a 48-lead LFCSP and can be operated from a single 3.3 V supply. An external VCO, which requires an extended voltage range, can be accommodated by connecting the charge pump supply (VCP) to 5 V. A separate LVPECL power supply can be from 2.5 V to 3.3 V (nominal).The AD9517-4 is specified for operation over the industrial range of −40°C to +85°C.APPLICATIONS 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

The AD9522-51 provides a multioutput clock distribution function with subpicosecond jitter performance, along with an on-chip PLL that can be used with an external VCO.   The AD9522 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 AD9522 features 12 LVDS outputs in four groups. Any of the 800 MHz LVDS outputs can be reconfigured as two 250 MHz CMOS outputs.Each group of outputs has a divider that allows both the divide ratio (from 1 to 32) and the phase (coarse delay) to be set.The AD9522 is available in a 64-lead LFCSP and can be operated from a single 3.3 V supply. The external VCO can have an operating voltage up to 5.5 V.The AD9522 is specified for operation over the standard industrial range of −40°C to +85°C.The AD9520-5 is an equivalent part to the AD9522-5 featuring LVPECL/CMOS drivers instead of LVDS/CMOS drivers.1The AD9522 is used throughout this data sheet to refer to all the members of the AD9522 family. However, when AD9522-5 is used, it is referring to that specific member of the AD9522 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
