GENERAL DESCRIPTION

The AD9514 features a multi-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.

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 AD9514 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 ⅓ V_S. The VREF pin provides a level of

⅔ V_S. V_S(3.3 V) and GND (0 V) provide the other two logic levels.

There are three independent clock outputs. Two of the outputs

are LVPECL, and the third output can be set to either LVDS or

CMOS levels. The LVPECL outputs operate to 1.6 GHz, and the

third output operates to 800 MHz in LVDS mode and to

250 MHz in CMOS mode.

The AD9514 is ideally suited for data converter clocking

applications where maximum converter performance is

achieved by encode signals with subpicosecond jitter.

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 another clock output can

be set by means of a divider phase select function that serves as

a coarse timing adjustment.

The AD9514 is available in a 32-lead LFCSP and operates from

a single 3.3 V supply. The temperature range is −40°C to +85°C.
