AD9513BCPZ

The AD9513 is a three-output clock distribution IC with low jitter and low phase noise for optimal data converter performance. The device is also suitable for other applications where phase noise and jitter are critical.

Three independent clock outputs can be set to LVDS or CMOS levels. In LVDS mode, the output operates at 800 MHz; In CMOS mode, the output operates at 250 MHz.

Each output has a programmable crossover that can be set to an integer crossover ratio of 1~32. The phase of one clock output relative to the other clock outputs can be set by the crossover phase selection function for timing coarse tuning.

One of the outputs provides a delay unit with three selectable full-scale delay values (1.5 ns, 5 ns, and 10 ns), all of which provide 16 levels of fine tuning.

The AD9513 can be operated or set up without the need for an external controller. The device is programmed with 11 pins (S0~S10) and 4 logic levels. The programming pins are internally biased to 1/3 VS. The VREF pin provides 2/3 VS level. VS (3.3 V) and GND (0 V) provide two additional logic levels.

The AD9513 is ideal for data converter clock applications that utilize sub-picosecond jitter encoded signals for optimal converter performance.

The AD9513 is available in a 32-pin LFCSP package, operates from a single 3.3 V supply, and has an operating temperature range of −40°C~+85°C.
