GENERAL DESCRIPTION
The AD9516-41 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 AD9516-4 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 AD9516-4 features six LVPECL outputs (in three 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.
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 AD9516-4 is available in a 64-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 AD9516-4 is specified for operation over the industrial
range of −40°C to +85°C.
1 AD9516 is used throughout to refer to all the members of the AD9516
family. However, when AD9516-4 is used, it refers to that specific member
of the AD9516 family.
