The AD9514 is a multi-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.
It offers 3 independent clock outputs, 2 of which are LVPECL and the 3rd output can be set to LVDS or CMOS levels. The LVPECL output can operate at a frequency of up to 1.6 GHz, and the third output can operate at a frequency of up to 800 MHz in LVDS mode and 250 MHz in CMOS mode.
Each output has a programmable crossover that can be set to integer crossover ratios from 1 to 32. The phase of one clock output relative to the other clock output can be set by the crossover phase selection function for timing coarse tuning.
The LVDS/CMOS outputs provide latency characteristics with three selectable full-scale delay values (1.5 ns, 5 ns, and 10 ns), all of which are available with 16 levels of fine tuning.
The AD9514 can be operated or set up without the need for an external controller. The device is programmed with 11 pins (S0 to S10) and 4 logic levels. The programming pin is 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 AD9514 is ideal for data converter clocking applications, utilizing sub-picosecond jitter encoded signals for optimal converter performance.
The AD9514 is available in a 32-pin LFCSP package and operates from a single 3.3 V supply. The temperature range is −40°C to +85°C.
