GENERAL DESCRIPTION

The AD9518-21 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 2.05 GHz

to 2.33 GHz. Optionally, an external VCO/VCXO of up to

2.4 GHz can be used.

The AD9518-2 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 AD9518-2 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 AD9518-2 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 AD9518-2 is specified for operation over the industrial

range of −40°C to +85°C.

AD9518 is used throughout the data sheet to refer to all the members of the

AD9518 family. However, when AD9518-2 is used, it refers to that specific

member of the AD9518 family.
