AD9515/PCBZ

AD9515/PCBZ is an evaluation board for AD9515 clock distribution IC. The AD9515 clock IC provides multioutput clock distribution in a design that emphasizes low jitter and phase noise to maximize data converter performance. The AD9515 offers two independent clock outputs, one as LVPECL, the other is selectable as either LVDS or CMOS levels. The LVPECL outputs operate to 1.6GHz, the LVDS outputs operate at 800MHz, and the CMOS outputs operate at 250MHz. Each output has a programmable divider, which 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 is set by means of a divider phase select function that serves as a coarse timing adjustment. The LVDS/CMOS outputs feature a delay element with three selectable full-scale delay values (1.8ns, 6.0ns, and 11.6ns) each with 16 steps of fine adjustment. The AD9515 clock IC does not require an external controller for operation or setup.

• AD9515 evaluation board requires a 3.3V power supply
