GENERAL DESCRIPTION
The AD9515 features a two-output clock distribution IC in a
design that emphasizes low jitter and phase noise to maximize
data converter performance. Other applications with
demanding phase noise and jitter requirements also benefit
from this part.
There are two independent clock outputs. One output is
LVPECL, while the other output can be set to either LVDS or
CMOS levels. The LVPECL output operates to 1.6 GHz. The
other output operates to 800 MHz in LVDS mode and to
250 MHz in CMOS mode.
Each output has a programmable divider that can be set to
divide by a selected set of integers ranging from 1 to 32. The
phase of one clock output relative to the other clock output can
be set by means of a divider phase select function that serves as
a coarse timing adjustment.
The LVDS/CMOS output features a delay element with three
selectable full-scale delay values (1.5 ns, 5 ns, and 10 ns), each
with 16 steps of fine adjustment.
The AD9515 does not require an external controller for
operation or setup. The device is programmed by means of
11 pins (S0 to S10) using 4-level logic. The programming pins
are internally biased to 鈪?V
S
. The VREF pin provides a level of
鈪?V

S
(3.3 V) and GND (0 V) provide the other two logic levels.
The AD9515 is ideally suited for data converter clocking
applications where maximum converter performance is
achieved by encode signals with subpicosecond jitter.
The AD9515 is available in a 32-lead LFCSP and operates from
a single 3.3 V supply. The temperature range is 鈭?0掳C to +85掳C.
