GENERAL DESCRIPTION
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 AD9518-3 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 AD9518-3 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

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 AD9518-3 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 AD9518-3 is specified for operation over the industrial
range of 40°C to +85°C.
1 AD9518 is used throughout the data sheet to refer to all the members of
member of the AD9518 family.
