The AD9517-31 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 1.75 GHz to 2.25 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.

The AD9517-3 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 AD9517-3 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 AD9517-3 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 AD9517-3 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

1 AD9517 is used throughout to refer to all the members of the AD9517 family. However, when AD9517-3 is used, it is referring to that specific member of the AD9517 family.

Product Detail

The AD9516-x, AD9517-x, and AD9518-x are very low noise PLL clock synthesizers featuring an integrated VCO, clock dividers, and up to 14 outputs. The AD9516 features automatic holdover and a flexible reference input circuit allowing for very smooth reference clock switching. The AD9516 family also features the necessary provisions for an external VCXO.

The AD9516 evaluation board is a compact, easy-to-use platform for evaluating all features of the AD9516. The AD9516, AD9517, and AD9518 differ only in package size, and the number of outputs. The evaluation software main window for the AD9517 and AD9518 reflects fewer outputs, but the operation is identical for all devices.

Use the user guide in conjunction with the AD9516, AD9517, and AD9518 data sheets.
