●Product Details
●The AD9518-01 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 2.55 GHz to 2.95 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.
●The AD9518-0 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 AD9518-0 features six LVPECL outputs (in three pairs). The LVPECL outputs operate to 1.6 GHz.
●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 AD9517 are similar to the AD9518 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 AD9518-0 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 AD9518-0 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

●1 AD9518 is used throughout the data sheet to refer to all the members of the AD9518 family. However, when AD9518-0 is used, it refers to that specific member of the AD9518 family.
